Euro coins vary in size, weight, colour and thickness depending on the denomination. They each have one common side and one country-specific side.
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.
