10 ECU - Beatrix Geert Groote

The ECU — European Currency Unit — was never legal tender in the conventional sense but existed as a basket currency used in EU financial settlements and exchange rate mechanisms. The Netherlands issued collector ECU pieces throughout the late 1980s and early 1990s under a cultural series framework, with this piece honoring Geert Groote, the 14th-century Deventer mystic and founder of the Devotio Moderna movement, whose followers eventually produced the Imitatio Christi. The X prefix in the KM reference system flags it as a non-circulating issue — struck for the collector market, not for monetary use.
