Katangese Franc
The franc was the currency of Katanga between 1960 and 1963 during the Congolese province's brief independence. It replaced the Congolese franc at par and was consequently initially equal to the Belgian franc. This established an exchange rate of 50 francs = 1 U.S. dollar. Just before Katanga was re-annexed by Congo, the exchange rate had fallen to 195 francs = 1 U.S. dollar. The currency was replaced at par by the Congolese franc.
