Franc
The Swiss franc (ISO code: CHF or 756), which appreciated significantly against the new European currency from April to September 2000, remains one of the world's strongest currencies, worth today around five-sixths of a euro. The Swiss franc is used in Switzerland and in Liechtenstein. Liechtenstein retains the ability to mint its own currency, the Liechtenstein franc, which it does from time to time for commemorative or emergency purposes.
Economy of Kosovo
The euro is the official currency of Kosovo. Kosovo adopted the German mark in 1999 to replace the Yugoslav dinar, and later replaced it with the euro, although the Yugoslav (and later Serbian) dinar is still used in some Serb-majority areas (mostly in the north). This means that Kosovo has no levers of monetary policy over its economy, and must rely on a conservative fiscal policy to provide the means to respond to external shocks.
