1 Franc - Louis II

Monaco's 1943 coinage was produced under Italian occupation, and the principality had virtually no independent monetary infrastructure of its own — these aluminum-bronze pieces were struck at the Paris Mint under Vichy-era administrative arrangements. Louis II, then in his late seventies, had little practical authority over the terms of production.

The copper-aluminium alloy was a wartime substitution driven by metal shortages, replacing the nickel issues of the prewar years.
