To solve this problem, the new Swiss Federal Constitution of 1848 specified that the federal government would be the only entity allowed to issue money in Switzerland. This was followed two years later by the first Federal Coinage Act, passed by the Federal Assembly on 7 May 1850, which introduced the franc as the monetary unit of Switzerland. The franc was introduced at par with the French franc. It replaced the different currencies of the Swiss cantons, some of which had been using a franc (divided into 10 "batzen" and 100 "centimes") which was worth 1.5 French francs.
