0 Euro - Velbert Schloss und Beschlägemuseum

Velbert, a small city in the Bergisches Land region of North Rhine-Westphalia, claims an outsized place in the history of locks and security hardware — the area accounts for a disproportionate share of Germany's lock and key manufacturing, a trade concentrated there since the 17th century. The Schloss und Beschlägemuseum documents that industrial heritage specifically, making it an unusual subject for the EuroSouvenir programme, which more typically leans on cathedrals and castles.

Oberthur Fiduciaire prints the entire EuroSouvenir series under license from the ECB, which mandates the "0 Euro" denomination to prevent these from functioning as legal tender while still allowing them to carry genuine security features.
