The Vatican City State, the Italian Republic, the Republic of San Marino, and the Sovereign Military Order of Malta, issued on September 7, 2025, two joint postal issues to celebrate the canonization of Blessed Carlo Acutis and Pier Giorgio Frassati. The four postal entities issued stamps based on the same pictures, on one side a portrait of Pier Giorgio Frassati (1901-1925), by the painter Alberto Falchetti (1878-1951), owned by the Frassati family, on the other one, a photograph of Carlo Acutis (1991-2006), during one of his last school trips before his untimely death. The canonization took place on Sunday, September 7, 2025, in St. Peter’s Square, presided over by Pope Leo XIV. Details about stamps are not yet available, but reproductions were provided by Enzo Cafaro, Italy.
Both previous blog pages triggered attention from collectors and resulted in additional information that help complete the catalogue:
Regarding the Arab Postal Day issue [T20250803], two additional countries have to be added to the already reported list (Algeria, Iraq, Tunisia, and the United Arab Emirates) namely, Egypt and Oman which issued their stamps respectively on August 3, 2025 and August 10, 2025 (Information provided by Mohamed Achour Ali Ahmed, Algeria and Ali Allawati, Oman).
The 80th Arab League anniversary issue from March 22, 2025 [T20250322] was also completed by two stamps issued in miniature sheets of 3 pairs from the United Arab Emirates. These stamps were issued on August 18, 2025 (Information provided by Kenneth Sequeira, Singapore).
The previous blog page was also missing the image of the Russian stamp jointly issued with North Korea on August 15, 2025. Illustration was provided by Kenneth Sequeira, Singapore, confirming the twin character.
I also made a comment earlier that embroided stamps are never used postally. Henri Aronis (France) provided a proof that this can happen with a Swiss stamp (year 2000), although not part of a joint issue. As expected, the thickness of the ‘stamp’ makes cancellation illegible. This cover was sent from Switzerland to Niger. Thanks Henri.
Jaap Sarelse (the Netherlands) reacted on the comments provided earlier about the July 5, 2025 Cape Verde – Portugal joint issue and at the same time provided information about Angola, a third country joining this issue, with the following:
“The text suggests that it is a joint issue in which only Cape Verde and Portugal are involved. However, Angola is also involved with an identical stamp. Not to commemorate Angolan independence, but purely focused on the independence of Cape Verde. Some evidence:
In the leaflet of the Portuguese Post (6 pages) the text on page 5, 7th and 8th line from the bottom reads: ‘To help consolidate the historic memory of the founding of the Republic of Cabo Verde, a joint stamp issue is being released by Angola, Cabo Verde and Portugal’.
On page 5, one can find the stamps of Angola on the top row. Cabo Verde is also mentioned on this stamp at the bottom right.
Finally, only Cabo Verde is mentioned in the logo on page 1. I suspect that in the context of ’50 anos Independência Nacional’ Angola will get its own joint issue and that the name Angola will then adorn below the stars in the logo“
Thanks, Jaap for this complement. Catalogue will be updated. Here are the additional illustrations (Angola stamp illustrations provided by Kenneth Sequeira):
Additional information relative to issues to come include the following:
The Oman – Russia originally scheduled for April 22, 2025, is now postponed to September 26, 2025 (Oman source) or October 15, 2025 (Russian source), not clear at this stage. It will show maps and honour Omani explorer Ahmed bin Majid and the Russian traveler Afanasy Nikitin
Kenneth Sequeira reported also two modifications in the Russian philatelic programme for 2025: a) the RCC stamps will be issued on August 23, 2025, but over the past years these stamps involving all CIS countries were not anymore considered as joint and there is no hint that this will change this year; b) the anniversary of the liberation of Korea will be celebrated by overprinting the August 15, 2025 joint issue with North Korea. These stamps will be issued on September 2, 2025
On October 7, 2025, the France – Japan is also confirmed. Japan stamp designs became available (information provided by Dominique Josse, France)
On August 15, 2025, Argentina issued a stamp to celebrate 60 years of immigration from Korea. No stamps related to the same topic was seen so far in the South Korea philatelic program. This issue may remain unilateral (information provided by Enzo Cafaro, Italy)
Our friend Luis Alejandro Malanco Reyes (Mexico) is working on a Mexican stamp catalogue (which of course includes also joint issues involving Mexico) and brought on line the first part of his work (years 2001-2025) with free access: Catálogo Filatélico México . Congratulations Luis and keep doing the good job.
Finally, some information about the next joint crypto-stamps issue (not recommanded to include in the joint issue collection as explained earlier): This will be the fourth crypto joint issue after the 2022 Austria-Netherlands (Ox), 2023 Austria-Luxembourg-Netherlands (Lion) and 2024 Austria-Belgium-Luxembourg-Netherlands (dragon) issues. The theme for this fourth issue is the Greek world of the gods. Five countries will participate and they made the following choice: Portugal – Poseidon, Austria – Zeus and Hera (2 stamps), Belgium – Athena, Luxembourg – Artemis and the Netherlands – Hermes.
Jaap Sarelse has succesfully created joint stamp covers with the previous crypto stamps and will try again this year with the six stamps. He provided the picture of the copy from year 2024. Such documents are close to unique.
The catalogue was update with all above new data. See updated Vol 1, Vol 15 and Vol 16
Enzo Cafaro (Italy) completed the information about the dove issue described in a previous post and enhanced the list of participating countries. He provided also the picture of all to be produced items. The country list includes now : Aland, Armenia, Austria, Cyprus, Faroe Islands, Greenland, Liechtenstein, Luxembourg, Switzerland and United Nations (offices of Geneva, New York and Vienna, as well as UPU). By adding all the denominations we reach a total of about 75 Euros for 13 stamps that will never be used on real covers ! Our friend Jaap Sarelse (the Netherlands) will try to create some mixed FDC covers when stamps will be available. We wish him good luck as even the cancellation on such thick stamps (embroidery) may be tricky. If he succeeds, we promise to show results in these pages 😉
Luis Malanco (Mexico) provided some additional information regarding the Ecuador stamps issued on July 28, 2022, together with Mexico [T20220728] and honoring Leona Vicario and Manuela Saenz. The Ecuadorian stamps were issued at a much lower number than initially announced. The stamp was produced at only 2,000 samples, while the souvenir sheet only at 450 units. Those are the figures appearing in the official leaflet published by the “Servicios Postales del Ecuador”.
By coincidence, a forgotten issue was discovered recently by comparing data in the Michel Rundschau Catalogue. On December 29, 2022, Cambodia and Colombia issued twin stamps at the occasion of the 50th anniversary of diplomatic relationship between both countries. The stamps show a view of Ankor Wat and the Grave in the Archeological National Park of Tierradentro. This issue has not been reported so far and will of course be integrated in the catalogue. The difficulty will now be to find the stamps and not only reproductions.
During the year 2021, Colombia celebrated the 200th anniversary of its independence. Numerous stamps related to this event were issued during this year, which correspoded also to the first recognition of Colombia by other countries. By end of 2022, a first joint issue with Mexico was released (December 20, 2021). Surprisingly, during the following year of 2022, Colombia created a series of different stamps celebrating diplomatic relationships with different countries (not necessarily based on 200 years, but at least on rounded numbers): Egypt (February 23, 2022), USA (May 2), South Korea (May 6), Peru (May 27), Germany (August 5), Cambodia (December 29) and Chile (December 29. This type of issues continued the following year with Barbados (December 18, 2023), Canada December 22) and Argentina (December 23). During the year 2024, only stamps celebrating relationships with Sweden were released (exact issue date is unknown). Among all these stamps, and to our knowledge, only four translated in true joint issues, including Mexico [20211220], Peru (T20220527], Cambodia [C20221229], and Argentina [T20231223]
The design of the North Korean stamps to be released jointly with Russia on August 15, 2025 has been released. We have not seen yet the Russian stamps, but this country confirmed stamp issue in this honour at the same date. Design could be similar.
Last minute information: Kenneth Sequeira just provided information about stamps released by the Philippines on August 5, 2025, jointly with India, celebrating the 75th anniversary of their relationship. Each country issued a pair of identical stamps showing flowers. Note that despite being issued in 2025, the stamps celebrate an anniversary that took place in 2024.
On August 3, 2025, Arab countries join to celebrate the Arab Postal Day with a stamp showing an identical design ‘Towards more innovative postal services’. So far, this issue involves Algeria (August 3), Iraq (August 3), Tunisia (August 3), and United Arab Emirates (August 3). More countries will probably be added (Information provided by Mohamed Achour Ali Ahmed, Algeriaand Kenneth Sequeira, Singapore).
Additionally to earlier information related to the 80th anniversary of Arab League [T20250322], Kenneth Sequeira (Singapore) informed us that Sudan issued three stamps with three different denominations, not a single one as previously announced.
In the meantime, Qatar became also another country to be added to this series. The stamp was issued on June 15, 2025. There are still some chances that additional Arab countries will have to be added to this series.
On July 25, 2025, Indian Prime Minister Narendra Modi and Maldives’ President Dr. Mohamed Muizzu jointly released commemorative postage stamps marking 60 years of diplomatic relations between India and the Maldives. The stamps show local boats. For India, an Uru, i.e., a wooden dhow built by hand in Beypore, Kerala. For the Maldives, a Vadhu Dhoni, i.e., a traditional fishing boat widely used for reef and coastal fishing in the Maldives. Detailed pictures from the Maldives are not available yet (Information provided first by Kenneth Sequeira, Singapore)
Maldives intends also to issue twin stamps with Singapore on August 29, 2025. A pair of identical stamps will be produced by each country, with an additional souvenir sheet containing both stamps for Singapore. The stamp design was unveiled during a ceremony that was held on June 30, 2025. So far, only bad quality images were available (Information provided by Don Birschel, USA).
The 2025 EUROMED issue is dedicated this year to European resources. Almost full freedom was given to the postal administrations to design their stamps, and, as a consequence, individual stamps describe very different topics including national parks, natural (local) or energy resources (wind and sun), landscapes, food, crafts or access to raw material (e.g., salt), with Türkiye showing in a souvenir sheet all possible country resources. So far, 14 countries have released their stamps with the most ciommon date on July 14, 2025. Those countries include: Bosnia Herzegovina (July 10, 2025), strawberry tree (Arbutus unedo) derived products, preserves, jam; Croatia (July 14), the Neretva Delta; Cyprus (July 9), wind turbine; Egypt (July 14), energy, oil, sea resources; France (July 11), sea and shore; Greece (July 7), sea sponge (Spongia mollissima) and boat; Malta (July 9), sculptor and building; Montenegro (July 14), Ulcinjska Solana (Ulcinj saltworks); Morocco (July ?), natural resources, “Cap des Trois Fourches” (Cape of the Three Forks), Ramsar wetland; Portugal (July 10), carob collecting and salt harvesting; Slovenia (July 11), karst edge; Spain (July 8), flower (Paeonia cambessedesii), Balearic peony; Tunisia (July 7), Galite and Zembra national parks; Türkiye (Turkey) (July 7), landscape with different resources.
The Euromed association includes also Albania, Algeria, Jordan, Lebanon, Palestine. With the exception of Albania which always issues their Euromed stamp with a delay of one year, there is limited chances that one of these other countries will participate this year, but who knows?
Information was mainly provided by Med Achour Ali Ahmed (Algeria) and Enzo Cafaro (Italy). Thanks to both of them.
New information about joint stamp issues was gathered over the past weeks:
Sudan is a country to be added to the joint issue already involving Algeria, Egypt and Tunesia, celebrating the 80th anniversary of the Arab League (1945-2025) and that is described under [T20250522]. The exact date of issue of the Sudanese stamp is unknown, but probably the same as for the other countries, namely May 22, 2025 (information provided by Kenneth Sequeira, Singapore).
Same additional information regarding the AICEP issue from May 13, 2025: Guinea-Bissau is also a country to be added to Angola, Brazil, Cape Verde, Macau and Portugal that have issued identical stamps at the same date. Guinea-Bissau issued one stamp in miniature sheets of 8 stamps [3×3] with central label and a souvenir sheet with a single stamp. We are still waiting for information about stamps from Mozambique, Sao Tome Principe and Timor.
On May 23, 2025, the 1100th anniversary of the Kingdom of Croatia and the coronation of King Tomislav was celebrated by the issue of identical stamps involving Bosnia Herzegovina (Mostar) and Croatia. This twin issue shows a bas-relief of the King Tomislav holding a scepter. BH Mostar issued the stamps in miniature sheets of 8 units ([3×3] including a central label) at only 5,000 samples, while Croatia issued 50,000 stamps in panes of 25 stamps and 5 labels [5×6].
The Dove of Peace project is progressing. Around September 20, 2025, ten to twelve European countries will issue an identical embroidered stamp with an equivalent denomination of about 10 Euros. Confirmation of participation is reported from Aland, Liechtenstein, Luxembourg, Faroe Islands and Greenland. These countries are all part of the SEPAC (Small European Postal Administration Cooperation – https://www.sepacstamps.eu/) which every year since 2007, issues by end of the Summer, a series of stamps with a common topic. If this embroided stamp corresponds to the 2025 SEPAC issue, this will be the first time that the SEPAC countries agree on a twin issue. Other countries including Gibraltar, Iceland, Isle of Man, Jersey, Malta, Monaco or Vatican City could in this case also participate. Over the past year, there was always at least one country not participating, so there is no guarantee that all twelve countries will be involved. However, Austria and Armenia have also already announced their participation, so, in the best case it could become an extended SEPAC issue (without mention of the SEPAC word on the stamp). We also have to wait to complete the information about this new series (information provided by Jaap Sarelse, the Netherlands).
The 50 years of independence of Cape Verde was celebrated commonly with Portugal on July 5, 2025, with the issue of two identical stamps. Only limited information is available so far from Cape Verde. The 50th anniversary of the independence of Angola will be celebrated on November 11, 2025 which could also result in an Angola – Portugal joint issue on that day.
Finally, we would like to thank Sherman Nassif (USA) for a financial donation that will help cover part of the web site fees.
All the above information was integrated in the catalogue Vol 16.
Complementary information came from diverse collectors over the past three weeks. They are reported here, without any sense of priority.
Wayne Chen (USA) came across a vast number of se-tenant sheets fabricated and sold by Stampera. The full list is available through the companies’ site using the search tool and the word ‘siamese’ (reminder: in the joint issues definition, this word has to be replaced by ‘se-tenant’) https://stampera.eu/stamps?search=Siamese&page=1. As mentioned several times in the past in these pages, products released by this company are true stamps, but produced only for collectors in small amounts, without topic related to the country, and at a very high number of sub-types (souvenir sheets, miniature sheets, perforated and not) also with very high denomination. They are not called cinderellas, just because they show a denomination. A collector who wants to buy the complete set of these ‘se-tenant’ products (35 different products have been identified so far) will have to spend at least € 1,900 (souvenir sheets, perforated and non-perforated, both mint or FDC, without taking in account individual isolated stamps). All these products are simply made to fool collectors and cannot be approved as true joint issue. With the new printing technologies, they are also suspected to be printed upon demand only, i.e., sheet by sheet, so there is no limitation in terms of printing runs. In this case, they will not be reported in the catalogue, but we wanted to bring this information to your attention.
All described products have been printed by associating in a same miniature sheet, stamps from up to 6 different countries, available normally in panes. Some examples are provided below.
Robert Schrijvers (Mongolia) talked with Mongol Post about the potential joint issue between India and Mongolia intended to celebrate the 70th anniversary of diplomatic relations (December 1955 ?). These relations were initiated on December 24, 1955. Robert has seen the Mongolian version, but was not allowed to take a picture. It depicts Mongolian (biyelgee) and Indian dances. Decision to release and date of issue are pending upon Indian Post agreement.
Milan Csaplár (Slovakia) provided the design of the joint issue to be released in August 2025, by the Slovak Post and the Luxembourg Post, which is dedicated to King Sigismund of Luxembourg (640 years of the crowning of Sigmund of Luxembourg in Hungary).
Ali Allawati (Oman) points to an error in the catalogue regarding the image of the Oman stamp from the Oman–Singapore joint issue [T20250221]. This mistake appears in both the blog and the catalogue. The image of the stamp currently shown is taken from the souvenir sheet, which does not display a denomination. The actual stamp is priced at 500 Baisa. The stamp on the souvenir sheet does not display a price. The souvenir sheet price can be seen in the bottom left corner of the souvenir sheet. Below, in the reproduction, you can see the differences between the two stamps, the second one taken from the souvenir sheet, next to the complete souvenir sheet with denomination in the margin. This mistake was corrected in the catalogue. Thanks Ali.
Ali provided additionally, a corrected version of the image used for the Oman–Iran joint issue from May 27, 2025. In the previous blog page, the illustration contains an error at the level of the title at bottom right, in which ‘Grand’ was mistakenly spelled ‘Ground’. This is corrected in the final version and to our knowledge, no stamp with the mistake was released. Both souvenir sheets (design left with mistake and final, corrected, right) are reproduced below. We are still missing information from Iran.
On the other hand, we are also waiting information about the Oman – Russia joint issue announced in the press for a release on April 22, 2025.
Kenneth Sequeira (Singapore) found the design of the next Peru –Türkiye joint issue to be released in the second half of 2025, to commemorate the 75 years of relationship. No idea if both stamps will show the same design.
The issues involving Bosnia Herzegovina (Croatia) and Bosnia Herzegovina (Serbia) commemorating the 150th anniversary of the Herzegovina uprising, translated in two different stamps, issued at two different dates respectively June 15 and June 19, 2025, but above all, without any joint character, i.e. not claimed as joint by the two postal authorities. These stamps are to be considered as a simple anniversary commemoration, around the same date, and will not be included in the catalogue.
The catalogues Vol 1 and Vol 16 have been updated accordingly.
Upon a proposal from Portugal, the five lusophone countries Angola, Brazil, Cape Verde, Macau and Portugal came together to celebrate with a twin issue the 35th anniversary of AICEP (Associação Internacional das Communicaçóes de Expressão Portuguesa – International Association of Portuguese Expression Communications). Stamps with the same design were all released on May 13, 2025, during the XXXII AICEP forum.
This AICEP anniversary issue could include the other countries members of the association, namely Guinea Bissau, Mozambique, Sao Tome and Principe and Timor, but so far no information is available from these countries (images provided by Enzo Cafaro, Italy and Kenneth Sequeira, Singapore – Image from Angola is still missing, although participation is confirmed).
In the previous blog page, we described souvenir sheets released on April 25, 2025 by Belarus and Russia to commemorate the 80th anniversary of the victory of the Soviet people in the Great Patriotic War (1941-1945). Kenneth Sequeira, Singapore, reported stamps issued by Kazakhstan and Mongolia at the same occasion. The Kazakhstan souvenir sheet including a round stamp was issued also at the same date of April 25, 2025 and must be added to the previous countries. This souvenir sheet, printed only at 2,500 samples, became also available with a “PCC/RSS” overprint (Regional Commonwealth in the Field of Communication) within the stamp, not related to this joint issue. Mongolia produced a completely different stamp in sheetlets of 4 [2×2] released on April 30, 2025. It is not clear if this fourth country participated to a joint effort with the three other countries, and for the time being these stamps will only be described as a footnote in the same entry.
Enzo Cafaro, Italy, was able to provide the preliminary sketches of the joint issue between the RussianFederation and the Dominican Republic planned for July 17, 2025. The final design may still change slightly but illustrations show that it will be almost identical for both countries.
Some surprising self-named joint issues appeared over the past months. The first one is related to the 90th anniversary of the relationship between Egypt and Switzerland. Egypt issued a stamp, but nothing was produced on the Swiss side. This Egyptian stamp will definitely remain an unilateral issue.
Also, Cambodia and Cyprus revealed by mid May (19 or 20) a so-called joint issue commemorating the 25th anniversary of their relationship. This information appeared on a UPU Facebook blog page (confirming a kind of postal commemoration), but the design that is shown looks like a stamp only through the perforations: there is no identified single country mentionned on the stamp, nor a denomination. As additional information from both countries is missing, it may be possible that this picture is just the symbolic design of the anniversary framed with perforations, and not a stamp, or at least not the final design. More information is needed here.
Ali Allawati, Oman, provided information from his country: next to the recently issued joint issue between Oman and Singapore reported under T20250221, Ali describes first an Iran-Oman issue (see illustration below), announced on May 27, 2025, issued in honour of the official Visit of His Excellency Dr. Masoud Pezeshkian, President of the Islamic Republic of Iran, to the Sultanate of Oman. The Oman stamp is not yet available for purchase, and information is missing from the Iranian side.
On April 22, 2025, Oman Post had also annnounced the issuance of a joint stamp celebrating the enduring relations between the Russian Federation and Oman, coinciding with the state visit of His Majesty Sultan Haitham bin Tarik to Russia. At this stage this is the only information available.
To the already very large October 9, 2024 UPU joint issue, one has also to add Aruba as a new country, which released a souvenir sheet containing a triangular shaped stamp, showing the UPU 150th anniversary logo in the margin. The souvenir sheet was issued on October 9, 2024, but was discovered only recently.
For those interested in the 2025 Europa stamps, this is the status of the issuing programme. The stamps with common topic National archeological discoveries (which topic was postponed to 2025 from originally 2024), were issued with a date centered around May 9, 2025. This year, these stamps are not considered as joint and will be reported under a simple list entitled [N20250509]. In the following list, empty bracket represent countries that announced their participation but from which data and in particular issue date are still missing, while absence of date means that those stamps were issued on May 9, 2025: Aland – Albania () – Andorra (French) (May 11) – Andorra (Spanish) – Armenia (April 29) – Artsakh (Armenia) () – Austria (May 1) – Azerbaijan (May 5) – Azores – Belgium (April 7) – Bosnia Herzegovina – Bosnia Herzegovina (Croatia) (April 5) – Bosnia Herzegovina (Serbia) (April 24) – Bulgaria – Croatia – Cyprus – Cyprus (Turkish) (May 8) – Czech Republic (May 7) – Denmark (May 28) – Estonia – Faroe (May 26) – Finland (May 7) – France – Georgia – Germany (May 8) – Gibraltar (May 8) – Greece (May 7) – Greenland (May 26) – Guernsey (May 1) – Hungary – Ireland (May 8) – Isle of Man (April 8) – Italy – Jersey (May 5) – Kazakhstan () – Latvia – Liechtenstein (April 1) – Lithuania (April 25) – Luxembourg (May 6) – Macedonia (North) (May 7) – Madeira – Malta – Moldova (April 11) – Monaco – Montenegro – Netherlands – Norway (April 24) – Poland (April 28) – Portugal – Romania (April 29) – San Marino (February 11) – Serbia (May 6) – Slovakia (April 30) – Slovenia – Spain – Sweden (April 24) – Switzerland (May 8) – Türkiye (Turkey) – Ukraine (August) – Vatican (May 27)
Eventually, we learned also that a new crypto-stamp joint issue involving Austria, Belgium, Luxembourg, the Netherlands and Portugal. Details will be known during the summer.
Belarus and Russia finally released the stamps celebrating the “Memory train cultural and educational project”. This issue that was announced several times with date of issue that changed from May 6 to April 17, 2025. Finally stamps became available on April 18, 2025. The identical stamps represent the train and are produced in miniature sheets of 12 [3×4] for Russia and miniature sheets of 6 [2×3] for Belarus.
‘The Memory Train is a Russian-Belarusian cultural and educational project aimed at uniting young people from different countries, forming a respectful attitude and understanding of the significance of the heroic feats of previous generations, and introducing them to the culture and traditions of neighboring countries. Participants of the Memory Train set off on a journey along a route that includes visits to hero cities, memorial complexes, museums, places of military glory and other memorable places. The Memory Train helps to preserve the connection between generations, passing the baton of memory from veterans to young people who will become the guardians of this history in the future’.
The second Belarus-Russia joint issue of April 25, 2025 is dedicated to the ‘80th Anniversary of the victory of the Soviet people in the Great Patriotic War’. Both souvenir sheets have a completely different design. Russia has also released the souvenir sheet in a numbered embossed version (Jaap Sarelse, the Netherlands).
On May 7, 2025, Liechtenstein and Switzerland issued a series of new crypto stamps as a joint issue (information provided by Jaap Sarelse, the Netherlands). The stamps of both countries are different but form a continuous image when placed next to each other. They represent landscapes of both countries with half a cow head each. The cow is available in 6 colors, green issued at 7,500 samples in each country among which 2,500 were used in combined mixed FDCs, blue at 3,250 samples (with 1,250 for FDCs), yellow 1,250 (250 FDCs), orange 300 (100 FDCs), pink 150 (30 in FDCs) and rainbow issued at 50 samples in each country among which 10 were taken to create mixed FDCs. Digitally, from the QR code, both stamps can later be combined into a whole that results in a moving cow on the screen. Sales prices are also proportional to the scarcity: while the official denomination is CHF 8.50 for all items, miniature sheets with green cows are sold at CHF 9.90 (about 10.60 €), blue at € 29, yellow at € 99, orange at € 199, pink at € 299 and rainbow at € 499. Mixed FDCs with the same color cows are sold between €29 for the green pair and €1,999 for the rainbow pair. A full series of mint stamps would amount to about € 2,000, and the full series of mixed FDCs would reach about € 4,200, but this is already impossible to complete as only green, blue and yellow stamps remain available for purchase, consequence of the very low printing runs.
These stamps will be reported in the catalogue for the completeness of information, but the high prices and the low levels of production exclude them from being considered as ‘normal’ items for collection, like for all previous crypto stamps issued so far. We do not recommend to buy them as they have been produced mainly for speculation purpose. They are more to be considered for coin/currency collectors than for stamp collectors, also as they will never be found on a mail that will have really circulated (for which they are normally intended). The fact that at the time of writing, all 7,500 samples of the green cow stamps have not been sold, demonstrates clearly the absence of interest of philatelists for these products which eventually should not be labelled as ‘stamps’.
Just as a reminder: one can find on the net a mixed cover with Panama (April 3, 2024) and Vatican (May 21, 2024) stamps that is presented as a mixed joint issue. While being a nice joint cover, the stamps on this item have not been accepted as joint issue and are filed under ‘non-accepted issue’ [N20240403] in the catalogue.
Enzo Cafaro (Italy) could confirm that the Argentina – Qatar issue is joint on the basis of an identical stamps., Argentina had issued its stamp on January 31, 2025 and Qatar released a souvenir sheet with one stamp on May 7, 2025. The issue is to be considered as Concerted and described in the catalogue under [C20250131].
Eventually, the Philippines conterpart of the Moroccan joint issue fron April 10, 2025, was also discovered. The quality of this first image is not as good as expected, but at least it confirms that the issue can be considered as twin (or concerted, as the date of issue of the Philippines stamps needs to be confirmed). The Philippines stamps were issued as se-tenant pairs available in a miniature sheet containing two pairs. Any additional information about this pair of Philippines stamps is welcome.
A China PR – Indonesia 75th anniversary of relationship commemorative joint issue whad been announced to be issued during April 2025. The Indonesia souvenir sheet was released, but, by beginning of May 2025, China had not announced anything in relation with Indonesia. Taking in account the shape and type of the Indonesian product, there are great chances that this will not translate in a real joint issue on the Chinese side. In the meantime, here is already the picture of the Indonesian souvenir sheet that was recently released.
On April 7, 2025, Portugal and India issued, as planned, a souvenir sheet each, commemorating the 50th anniversary of the re-establishment of their diplomatic relationship. The two common stamps feature the traditional costume from Viana do Castelo, Portugal, and the Kalbelia dance costumes, India (information first provided by Kenneth Sequeira, Singapore and Souvik Ghatak, India).
On April 10, 2025, Morocco issued a pair of stamps representing airports (Mectan – Cebu and Menara – Marrakech) and celebrating 50 years of relationship with the Philippines. So far, information from the Philippines is not available, although the stamps of this country have been announced, and taking in account the structure of the Moroccan issue, it could become a twin or concerted issue.
Med Achour Ali Ahmed (Algeria) provided complementary information about the Arab League 80th Anniversary stamps. The Egyptian issue is not a stamp in pane, but a souvenir sheet, size 120×85 mm, issued on March 22, 2025, at 7,000 samples only among which 700 were used to prepare first day covers. The denomination is 20 Egyptian Pounds. In the meantime, no information about an additional country participating to this issue became available.
Tolga Caglayankaya (The Netherlands) provided information about a new 150th UPU Anniversary country srtamp (T20241009). South Sudan issued two stamps and one souvenir sheet containing these two stamps, displaying the basic design. Apparently only 500 samples of the souvenir sheet were printed. The exact date of issue seems to be March 27, 2025.
Jaap Sarelse (The Netherlands) reported also about a stamp issued by Nigeria on October 10, 2024 but bearing the design of the October 9, 2022, World Post day issue. This stamp has of course been added to the T20221009 series.
The Arab League was formed in Cairo on March 22, 1945, and at the occasion of the 80th anniversary, the General Secretariat proposed a joint stamp issue based on a common design. Three countries, Algeria, Egypt and Tunisia issued a stamp on March 22, 2025. The design shows the logo of the League, a large figure “80” and the building of the headquarters in Cairo, Egypt.
The League was initially formed with seven members: Egypt, Iraq, Transjordan, Lebanon, Saudi Arabia, Syria, and North Yemen. Currently, the League has 22 members, i.e., Algeria, Bahrain, the Comoros, Djibouti, Egypt, Iraq, Jordan, Kuwait, Lebanon, Libya, Mauritania, Morocco, Oman, Palestine, Qatar, Saudi Arabia, Somalia, Sudan, Syria, Tunisia, the United Arab Emirates and Yemen, which all of them could theoretically participate to this joint issue. Information from the other 19 countries is awaited, not necessarily with a date of issue of March 22, 2025. Thanks to Med Achour Ali Ahmed (Algeria) and Kenneth Sequeira (Singapore) who provided the first information and pictures related to this issue.
