French franc
On 16 July 1947, banknotes were issued for Saar denominated in marks, which replaced the German Reichsmark. But in November 1947, the French government reintroduced the French franc as the official currency. Between 20 November 1947 and 15 January 1948, all notes and coins had to be exchanged at a rate of 20 Saar marks = 1 franc. In 1954 the government of the Protectorate issued new coins in denominations of 10, 20, 50 and 100 francs. The coins resembled the coins of the French franc (same metallic composition, size and weight) and were officially and legally not a currency of their own, but only local issues of the French franc.
