2 Francs - Louis II

Louis II had been on the Monegasque throne for only three years when this coin was struck, still navigating the terms of the 1918 Franco-Monegasque Treaty that had sharply curtailed Monaco's autonomy — including provisions giving France significant influence over succession. The copper-aluminium alloy was a post-war economic compromise adopted across several small European states still adjusting to metal shortages and inflated commodity prices following 1918.

Monaco's mintage figures for this period were extremely limited by the principality's tiny population, and relatively few pieces entered meaningful circulation.
