Common sides

Euro coins have one common side with the same designs across all euro-area countries, and a national side designed by each participating country. The common sides of the euro coins show three different maps of Europe, with a background including the 12 stars of the European Union.

The design of the common sides of the 10, 20 and 50 cent and 1- and 2-euro coins has been modified during 2007 to reflect the enlargement of the EU in 2004. The new common designs are being introduced progressively as from 2007, and will become mandatory for all new coin production from 2008.
