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.
Coat of arms of Switzerland
Alternative shapes of the heraldic shield were also in frequent use, and still remain in use in spite of the 2017 legislation. 
A frequently seen shield shape is the "Iberian" or "curved" type, specifically used to mark Swiss embassies and border crossings, and also used on the five franks coin. 
Another frequently seen variant is a Renaissance-style articulated shield, shown as being held by the national personification Helvetia on the ½, 1 and 2 franks coins.
