Saar franc

The Saar franc was the French franc (German: Franken) used as the official currency of the Saar during the times that the Saar territory was economically split off from Germany, in 1920–1935 as the Territory of the Saar Basin, in 1947–1957 as the Saar Protectorate and 1957–1959 as the state of Saarland in West Germany. Local notes and coins were issued during both periods, but the Saar franc was never legally an independent currency.
