The franc (ISO 4217: MCF) was the official currency of the Principality of Monaco until 1995 ("de facto", 1996 "de jure"), when it changed to the French franc. The franc was subdivided into 100 "centimes" or 10 "décimes". The Monégasque franc circulated alongside the French franc with the same value. Like the French franc, the Monégasque franc was revalued in 1960 at a rate of 100 old francs = 1 new franc. The official euro-to-franc exchange rate was MCF 6.55957 to EUR 1.
