0 Euro - Parc Branféré

Parc Branféré is a wildlife park and botanical garden in Le Guerno, Morbihan, operated since 1968 under the Fondation pour la Sauvegarde et le Développement du Patrimoine Universel. Zero-euro souvenir notes have been produced by Oberthur Fiduciaire since the format was commercialized around 2015, with individual sites commissioning their own designs in limited print runs — the business model means the park, not a central authority, controls distribution and quantity. No monetary value, no legal tender status anywhere, and Oberthur's security printing features are present purely to discourage counterfeiting of what is, functionally, a collector's ticket stub.
