The month of September led to more new products than the whole preceeding Summer period including some surprising items, next to the already reported PAPU issue (7 countries), the China-Hong Kong – Macau series and the Switzerland – South Korea stamps.

Don Birschel, USA, reported about an unexpected joint issue between Guatemala and Mexico, released on September 18, 2023 and related to the 175th anniversary of their relationship. The stamps represent the Pyramid of the Sun, San Juan Teotihuacan, Mexico and the Tempel of the Great Jaguar, Tikal, Guatemala (pre-Columbian Maya civilization). Don provided the images, but we are still missing some details about the Guatemala stamps.

The 200th anniversary of the relationship between Argentina and Brazil translated into a stamp showing the Iguazu falls at the Brazilian-Argentinian border, issued on September 7, 2023, while Brazil released on September 29, 2023, a panel of 8 stamps showing Mafalda comics from the Argentinian artist Quino. Despite the common title, this issue cannot be considered as joint (different dates of issue, different designs, no claim as joint – information provided by Enzo Cafaro, Italy).

On September 26, 2023, San Marino issued a stamp related to the 15th anniversary of relationship with Mexico. No Mexican counterpart was seen so far, and probably nothing has to be expected from the mexican side.

More recently, on October 2, 2023, Slovakia issued, jointly with Azerbaijan, stamps at the occasion of their 30 years of relationship, the same day Slovakia issued stamps with the Czech Republic (see previous blog page). This series describes folk music styles illustrated with string instruments: the Terchova region music and the Mugham Azerbaijani folk music. Azerbaijan has issued the stamps apparently only as a souvenir sheet at only 5,000 samples (Information provided by Eric Contesse, France).

A new crypto stamp (NFT) joint issue, to be released during the month of October 2023 (probably on the 23rd), was announced involving Austria, Luxembourg and the Netherlands. Stamps are similar. More details soon. For explanations about crypto stamps, see austria-netherlands-crypto-stamp.

There is still a problem with these new products: crypto stamps are always very expensive, their value is linked to crypto money that is fluctuating a lot over time (value of previous NFT stamps has dropped a lot recently) and above all, these so-called stamps are never used on real mail. To our opinion, they are more to be considered either as a piece of art or as a kind of currency, and seem to stay away from real philately (in terms of collecting items used to compensate for mail fees). Eventually, look like material to fool the collectors (abusive issues). Those stamps have to be reported in the catalogue as they are claimed as joint issue “stamps”, but there is no recommendation to buy them. On the other hand, a collection of such stamps on cancelled mail, i.e., for real non-philatelic mailing purpose, would be a real interesting topic. Apparently, in none of these countries, the denomination corresponds to a true postage fee and their use alone on a cover should not exist (except on FDC covers).
