Here are a few highlights visitors will find in their change:
Austria: Wolfgang Amadeus Mozart on the 1 euro coin.
Belgium: King Albert II on all coins.
Germany: Brandenburg Gate on the 10-, 20- and 50-cent coins.
Greece: On the 2 euro coin, a mosaic showing Europa being abducted by Zeus, who has taken the form of a bull. Europa is a mythological figure after whom Europe was named.
