Switzerland–European Union relations
The currency of Switzerland is the Swiss franc. Switzerland (with Liechtenstein) is in the unusual position of being surrounded by countries that use the euro. As a result, the euro is "de facto" accepted in many places, especially near borders and in tourist regions. Swiss Federal Railways accept euros, both at ticket counters and in automatic ticket machines. Also many public phones, vending machines or ticket machines accept euro coins. Many shops and smaller businesses that accept euros take notes only, and give change in Swiss francs, usually at a less favourable exchange rate than banks. Many bank cash machines issue euros at the traded exchange rate as well as Swiss francs.
Cupronickel
In Europe, Switzerland pioneered the nickel "billon" coinage in 1850, with the addition of silver. In 1968, Switzerland adopted the far cheaper 75:25 copper to nickel ratio then being used in Belgium, the United States, and Germany. From 1947 to 2012, all "silver" coinage in the UK was made from cupronickel, but from 2012 onwards the two smallest cupronickel denominations were replaced with lower-cost nickel-plated steel coins.
