フランス・フラン
When France adopted the euro, so did the French overseas departments and territories that used the French franc. The CFP franc, the CFA franc, and the Comorian franc, that are used in overseas territories and some African countries, had fixed exchange rates with the French franc, but not at par – for various historical reasons they were worth considerably less, at 1 French franc = 18.2 CFP francs, 75 Comorian francs or 100 CFA francs. The CFA franc and the Comorian franc are linked to the euro at fixed rates with free convertibility maintained at the expense of the French Treasury.
