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.
Austrian schilling
Although the euro became the official currency of Austria in 1999, euro coins and notes were not introduced until 2002. Old schilling denominated coins and notes were phased out from circulation because of the introduction of the euro by 28 February of that year. Schilling banknotes and coins which were valid at the time of the introduction of the euro will indefinitely remain exchangeable for euros at any branch of the Oesterreichische Nationalbank.
