0 Euro - Toulouse - La cité de l'espace

The zero-euro souvenir note program launched in France in 2016, with Oberthur Fiduciaire — one of the few security printers outside the Eurosystem's official supply chain — producing the series under license from the UEFC. La Cité de l'espace in Toulouse was among the inaugural batch of tourist sites to commission a note, which was a deliberate commercial move: the attraction opened in 1997 and had long sold conventional merchandise, but the notes proved unexpectedly popular as collectibles, prompting repeated reissues with altered serial prefixes that now constitute minor variants in their own right.
