0 Euro - Trakai

The 0 Euro souvenir program, administered by EuroSouvenir and printed by Oberthur Fiduciaire under license from the European Central Bank, launched commercially around 2015 and expanded rapidly across European tourist sites. Trakai — the medieval island castle in Lithuania — became one of hundreds of locations to commission a note. Oberthur's production standards are genuine: the paper, hologram strip, and intaglio-style printing match security specifications used on circulating currency, which is precisely why the ECB insisted on formal authorization before allowing the format at all.

These notes carry no legal tender status anywhere, though Lithuanian vendors occasionally accepted them as novelty payment in the program's early years.
