History of Switzerland
Switzerland's most important exports during the war were precision machine tools, watches, jewel bearings (used in bombsights), electricity, and dairy products. During World War Two, the Swiss franc was the only remaining major freely convertible currency in the world, and both the Allies and the Germans sold large amounts of gold to the Swiss National Bank. Between 1940 and 1945, the German Reichsbank sold 1.3 billion francs worth of gold to Swiss Banks in exchange for Swiss francs and other foreign currency.

All banknotes are quadrilingual, displaying all information in the four national languages. The banknotes depicting a Germanophone person have German and Romansch on the same side as the picture, whereas banknotes depicting a Francophone or an Italophone person have French and Italian on the same side as the picture. The reverse has the other two languages.
