5 Cèntims Sant Serni de Nagol

Andorra's early euro-era coinage occupied an odd liminal space — the country had no official currency of its own and used both French francs and Spanish pesetas simultaneously until those disappeared with euroization. These brass-composition centim pieces, issued under Andorran government authority, functioned as local subsidiary coinage while the country remained outside the eurozone proper, a status not resolved until the 2011 monetary agreement with the EU. Sant Serni de Nagol, an 11th-century pre-Romanesque church in the parish of Sant Julià de Lòria, was a deliberate choice to anchor the coinage in Andorra's architectural patrimony rather than its political institutions.
