0 Euro - Rennes - Anne de Bretagne

The zero-euro souvenir note program, launched commercially by Richard Faivre's Paris-based company in 2015, occupies an odd corner of the hobby — technically legal tender for zero euros, issued under European Central Bank authorization, but produced purely for the tourist and collector market. Oberthur Fiduciaire prints them to genuine banknote specification, which is precisely why they sell.

Anne de Bretagne, twice queen of France through successive marriages to Charles VIII and then Louis XII, remains a potent symbol of Breton identity — her 1532 union with the French crown through her daughter Claude is still a contested historical memory in the region.
