100 Francs - Rainier III Anniversary of Reign

Issued to mark the fiftieth anniversary of Rainier III's accession in 1949, this coin appeared just two years before his death in 2005 — though no one knew that at the time. Rainier's reign was the longest in Monaco's modern history, outlasting de Gaulle, four French Fifth Republic presidents, and the entirety of the Cold War. The Monnaie de Paris struck this piece under the longstanding treaty framework that grants France exclusive minting rights for Monégasque coinage, a arrangement codified in the 1918 Franco-Monegasque Treaty and reaffirmed through subsequent accords.
