1 ECU Europe "Tvaetur Unita Deus" Piedfort

The ECU was never legal tender in Greece — this is a collector-issue piedfort tied to the broader European push to familiarize citizens with a notional unit of account ahead of the Maastricht Treaty's monetary union timeline. Piedfort strikes, doubled in thickness against a standard flan, were a deliberate premium-market choice favored by several European mints in the 1990s to extract collector value from ECU enthusiasm before the currency was superseded entirely by the euro.

Greece ultimately adopted the euro in 2001, two years behind the initial eurozone cohort.
