0 Euro - Miniatur Wunderland Hamburg

Zero-euro souvenir notes occupy a peculiar niche — legal tender denominations are bypassed entirely, so Banque de France authorization covers the series without requiring any central bank involvement. Oberthur Fiduciaire produces these under a collector licensing scheme that began gaining momentum around 2015, with tourist attractions and cultural institutions across Europe commissioning their own issues. Miniatur Wunderland, the Hamburg model railway attraction that holds records for scale and visitor throughput, is precisely the kind of institution these notes were designed for.

Collectible by design, spendable by nobody.
