The Austrian €1 coin depicts Wolfgang Amadeus Mozart, one of the most important composers of the First Viennese School. His works are internationally popular and constitute some of the most important in the classical music repertoire.
Euro coins and banknotes were introduced on 1 January 2002 in twelve countries. Today, the euro area has grown to include 18 countries. Euro coins feature a common design on one side. Also, the national side (reverse) of every coin includes a ring of 12 stars from the European Union flag. Each country has its own design for the national side of its coins.
