Instructions
Look first for the word "Euro" or "Euro Cent." This is on the "common" side. In addition to this, the name of the currency, you should also see a denomination mark, either in cents or euros.
Continue looking at the common side of the coin. Besides the printed words, you will see one of two designs. The 1, 2 and 5 cent coins carry a motif of the globe of the Earth with the EU clearly marked upon it. The other coins depict the European coastline.
Turn the coin over and examine the "national" side. Depending on the denomination and which country in the EU issued the coin, there will be a different emblem. These emblems were chosen to reflect the styles and national identities of each issuing country--the harp for Ireland, the eagle for Germany, images from antiquity for Greece. For more help with identifying these national sides, see Resources.
