0 Euro - Nausicaá tortue et logo 2

Nausicaá, the marine centre in Boulogne-sur-Mer, has issued a steady stream of zero-euro souvenir notes since the format was commercially launched by the Euro Banknote Memory collector program around 2015. These are legal-tender novelties in the strictest technical sense — produced on genuine banknote paper by a licensed security printer — but were never intended to enter circulation and carry no redemption value at any central bank.

Oberthur Fiduciaire, one of the few private security printers authorized to produce euro-specification paper currency, handles the physical production. The zero-euro format has become a significant secondary revenue stream for museums and attractions across France.
