0 Euro - FCP - Estádio do Dragão

The zero-euro souvenir note format was formalized by the European Banknote Memory Organisation (EBMO) around 2015 and quickly became a significant collector sideline — Oberthur Fiduciaire secured the dominant share of that production, printing millions of these for tourist sites, museums, and sports venues across Europe. Legal tender status is nominal; the ECB tolerates rather than endorses them, and no central bank redeems them.

Estádio do Dragão, home of FC Porto, opened in 2003, built for UEFA Euro 2004. The watermark is the sole security feature retained from genuine banknote production — a deliberate choice to maintain the tactile credibility collectors expect.
