0 Euro - Technik Museum Sinsheim

The Euro Souvenir program launched in 2015 as a licensed novelty scheme, with Oberthur Fiduciaire producing these commemorative zeros on the same presses and security substrate used for genuine European currency — which is precisely the point. The watermark is not decorative; it's there because the notes are printed to De La Rue and ECB production standards, making them among the few legitimate souvenir items in the world that could pass a basic currency verification test.

Sinsheim's technology museum is home to a Concorde and a Tupolev Tu-144, the only site on earth displaying both supersonic passenger aircraft side by side.
