0 Euro La Montagne des Singes

La Montagne des Singes, a free-range Barbary macaque reserve near Kintzheim in Alsace, was among the early participants in the EuroSouvenir program when it launched in 2016. The zero-euro note scheme was the brainchild of Richard Faille, who licensed the concept through the Unioneuropéenne des fabricants de la monnaie (UEFL) — a private commercial venture, not a central bank initiative, though Oberthur's involvement gave the series genuine security printing credentials. The hologram strip is the same generation of feature used on circulating euro notes, which is precisely the point: these are legally issued instruments with face value zero, meaning they are not subject to counterfeiting law in the way commemorative fakes would be.
