The franc (unofficially MCF) was the official currency of the Principality of Monaco until 1995 (de facto, 1996 de jure), when it changed to the French franc which was replaced by the euro in 2002.

[2] The official euro-to-franc exchange rate was MCF 6.55957 to EUR 1.

The 5 centimes and 1 decime were minted in both copper and brass and were the same size as the earlier French coins (France was not minting these denominations at the time) whilst the 5 francs matched the French coin.

[5] Between 1924 and 1926, aluminium-bronze 50 centimes, 1 and 2 francs were issued of the same size as the French coins.

The embossed notes have a crowned shield with diamond pattern at center, encircled by the text Principauté de Monaco, and are available with circles of two different diameters.
