The gold franc was the unit of account for the Bank for International Settlements from 1930 until April 1, 2003. It was replaced with the special drawing right. It was originally based on the Franc Germinal, and remained at the value the franc was pegged (0.290g fine gold) after the countries of the Latin Monetary Union came off the gold standard.
The gold franc was used in the Anglo-French Condominium of the New Hebrides (now Vanuatu) as the currency in which the joint administration's postal service denominated its stamps. This added to the already confused situation in which the Australian dollar and the New Hebrides franc were used in normal trade (and in which even the pound sterling turned up the columns of earlier joint administration budgetary documents).
Swiss Gold Franc Initiative 
The Confederation institutes an official gold franc with a set of coins of different denominations, each having a fixed gold content. It regulates the concessions granted to the licensees authorized to mint coins; minting coins is not taxable.
This initiative was examined by the Committee for Economic Affairs and Taxation, which rejected it at the June meeting.
This gold franc would have been defined as 0.1 gram of fine gold. The initiative would not have removed, replaced or pegged the existing Swiss franc, therefore both the gold franc and the Swiss franc would have coexisted side-by-side. Due to the fixed metallic content of the gold franc, its exchange rate with the Swiss franc would have gone up and down according to market supply and demand, like any other free-floating currency.
The gold franc would have completely independent from the gold reserves of the Swiss National Bank. It would have been minted only by Swiss commercial banks, under the supervision of the Swiss Confederation. The backers of the gold franc hoped that its institution would have made it easier for small savers to invest in gold by reducing the minimum investment and trading unit.
