1 Diner Our Lady of Meritxell

Andorra's diner coinage occupies an odd corner of numismatic history — the country had no official currency of its own for centuries, relying on French francs and Spanish pesetas circulating simultaneously under informal arrangement. When Andorra finally began issuing its own coinage in the 1980s, the pieces were never legal tender in any practical sense; they were issued for collectors and tourists, not commerce. The country didn't gain formal monetary agreement with the EU until 2011, meaning this issue predates even that limited official status.
