0 Euro - Stuttgart - Schillerplatz

EuroSouvenir's zero-euro note program, launched in France around 2015 and printed by Oberthur Fiduciaire under license from the European Central Bank, occupies a legal grey area that took years to resolve — the ECB had to formally confirm that denominating a collectible note "0 Euro" did not constitute the unauthorized issuance of currency. Oberthur produces these on the same security substrate used for genuine euro banknotes, which means watermarks, UV-reactive ink, and microprinting are all present despite the note having no monetary function whatsoever.

The Stuttgart Schillerplatz issue is one of hundreds of location-specific variants in the program. Collector demand for individual sites varies sharply, and regional German subjects tend to sell out faster than comparable French ones.
