A silver coin of France, and since 1795 the unit of the French monetary system. It has been adopted by Belgium and Swizerland. In 1913 it was equivalent to about nineteen cents American, or ten pence British, and is divided into 100 centimes.
The franc is the name of several currency units, most notably the French franc, the currency of France until it adopted the euro in 2002; and the Swiss franc, still a major world currency today due to the prominence of Swiss financial institutions. The name is said to derive from the Latin inscription francorum rex ("King of the Franks") on early French coins, or from the French franc, meaning "free" (and "frank").
