0 Euro - Che Guevara

EuroSouvenir notes occupy a strange corner of modern notaphily — legal collectibles produced under license from the European Central Bank's souvenir banknote program, denominated zero to sidestep any legal tender complications. This Che Guevara issue is one of the more politically charged entries in the series, which more typically leans toward castles, regional landscapes, and heritage tourism.

Printed on polymer rather than the cotton-linen substrate of circulating euro notes, the watermark here is a design feature rather than a genuine security necessity — there's nothing to counterfeit.
