On October 21, 2024, a new joint crypto stamp series was issued involving Austria, Belgium (first Belgian crypto stamp), Luxemburg and the Netherlands, with topic dragon (2024 is Chinese year of the dragon). As representations of the dragons are different from one country to another, this issue is considered as parallel [P20241021]. Details about printing runs and colors of subtypes are provided in the catalogue. However, as for all crypto stamps, we continue to believe that these products are not real stamps (i.e. never used on mail) and closer to coins than to stamps, also with some good reasons to think they are products to fool collectors, we do not recommend to buy, except if you are an expert of crypto stamps and crypto money.
