0 Euro - Musée du circuit de Spa-Francorchamps

The souvenir zero euro program, administered under license from the European Central Bank, has produced thousands of these legal-tender-denominated novelties since 2015 — printed to genuine banknote specification by Oberthur Fiduciaire on security paper with the full complement of anti-counterfeiting features. The paradox is intentional: a note worth nothing, printed to the same standard as one worth something, sold for several euros at museum gift shops.

Spa-Francorchamps is the oldest active racing circuit in the world still hosting Formula 1, and the museum opened to formalize that history. R. Faille's signature appears as issuing authority rather than any central banking official — a quietly telling detail about where the line sits between currency and collectible.
