Title: French franc
Content:  The franc (sign: F or Fr), also commonly distinguished as the French franc (FF), was a currency of France. Between 1360 and 1641, it was the name of coins worth 1 livre tournois and it remained in common parlance as a term for this amount of money. It was reintroduced (in decimal form) in 1795. After two centuries of inflation, it was redenominated in 1960, with each new franc (NF) being worth 100 old francs. The NF designation was continued for a few years before the currency returned to being simply the franc; some mostly older French residents continued to reference and value items in terms of the old franc (equivalent to the new centime) until the introduction of the euro (for coins and banknotes) in 2002. The French franc was a commonly held international reserve currency of reference in the 19th and 20th centuries.
Title: Franc
Content:  The French franc was originally a gold coin issued in France from 1360 until 1380, then a silver coin issued between 1575 and 1641. The franc finally became the national currency from 1795 until 1999 (franc coins and notes were legal tender until 2002). Though abolished as a legal coin by King Louis XIII in 1641 in favor of the gold louis and silver écu, the term franc continued to be used in common parlance for the livre tournois. The franc was also minted for many of the former French colonies, such as Morocco, Algeria, French West Africa, and others. Today, after independence, many of these countries continue to use the franc as their standard denomination. The value of the French franc was locked to the euro at 1 euro = 6.55957 FRF on 31 December, 1998, and after the introduction of the euro notes and coins, ceased to be legal tender after 28 February, 2002, although they were still exchangeable at banks until 19 February, 2012.

Content:  Along with the Spanish peseta, the French franc was also a de facto currency used in Andorra (which had no national currency with legal tender). It circulated alongside the Monegasque franc in Monaco, with which it had equal value. These currencies were all replaced by the euro in 2002.
Title: Luxembourg franc
Content:  The Luxembourg franc (F or ISO LUF, Frang) was the currency of Luxembourg between 1854 and 1999 (except during the period 1941-'44). The franc remained in circulation until 2002, when it was replaced by the euro. During the period 1999–2002, the franc was officially a subdivision of the euro (€1 = 40.3399F) but the euro did not circulate. Under the principle of "no obligation and no prohibition", financial transactions could be conducted in euros and francs, but physical payments could be made only in francs, as euro notes and coins were not available yet. The franc was subdivided into 100 centimes.
Title: French Guianan franc

The French franc circulated alongside banknotes issued specifically for French Guyana between 1888 and 1961 and notes issued for French Guyana, Guadeloupe and Martinique (collectively referred to as the French Antilles) between 1961 and 1975. As an integral part of France, French Guiana is part of the European Union and the Eurozone, and starting in 2002, its currency is the euro.

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. Today, Monégasque coins have only numismatic value, including the fleurs de coins, or proof-like coins. The period for exchange of the coins for euros has expired.
