0 Euro - Charles de Gaulle : de l'Appel à la Libération

Fondation Charles de Gaulle has issued these commemorative zero-denomination pieces through Oberthur Fiduciaire since the format gained traction in France around 2015, initially through regional tourism boards before cultural institutions adopted it. They carry no legal tender status anywhere, manufactured specifically as collectibles under a licensing arrangement with the European Central Bank that permits the euro format provided the face value is printed as zero.

Oberthur's involvement is the one detail worth noting — the Tours-based printer holds security printing contracts across multiple African and European sovereign issuers, so the physical production quality here exceeds what the novelty premise might suggest.
