0 Euro - Paris - Musée de l'Armée

The zero-euro souvenir note program, launched by the European Souvenir Banknote Association in 2015, operates on a straightforward legal premise: a denomination of zero carries no monetary value and therefore falls outside the regulatory framework governing genuine currency issuance. Oberthur Fiduciaire prints them to full banknote specification — security thread, UV-reactive ink, intaglio printing — which is precisely what drives collector demand. The Musée de l'Armée, housed in the Hôtel des Invalides complex where Napoleon's tomb sits beneath the gilded dome, is among the higher-volume tourist venues in the series, meaning this particular issue circulates freely in the secondary market without significant scarcity premium.
