CFA franc
The CFA franc was introduced to the French colonies in West Africa in 1945, replacing the French West African franc. The West African colonies and territories using the CFA franc were Ivory Coast, Dahomey, French Sudan, Mauritania, Niger, Sénégal, Togo and Upper Volta. The currency continued in use when these colonies gained their independence, except in Mali (formerly French Sudan), which replaced at par the CFA franc with its own franc in 1961.
