0 Euro - Parque Warner Madrid

The Euro Souvenir program, administered under license from the European Central Bank, permits participating attractions to issue these legally denominated but non-circulating notes as collectibles — a commercial arrangement that has proven remarkably lucrative for Oberthur Fiduciaire, which holds a dominant share of the printing contracts across the series. Each note is assigned a unique serial number at the attraction's point of sale, making individual pieces theoretically traceable to a specific visitor on a specific date.

Parque Warner Madrid, the Spanish theme park operating under Warner Bros. Discovery licensing, joined the program in the early 2020s expansion push into Southern Europe.
