0 Euro - Caen - Le Mémorial 6 juin 1944

The 0 euro souvenir note program was launched by the European Banknote Memory Organization in 2015 and Oberthur Fiduciaire produced the first waves under strict ECB-compliant specifications — same security paper, same format as legal tender — deliberately making them difficult to counterfeit despite carrying no monetary value whatsoever. The Mémorial de Caen was among the earliest institutional adopters, which is fitting given that the museum itself was purpose-built for the 40th anniversary of the D-Day landings in 1988.

Oberthur's involvement ensured the notes carry genuine watermarks and security threads, a detail that surprises most collectors encountering the series for the first time.
