The €1 coin shows an image of an owl copied from an ancient 4-drachma coin. In the ancient world, the owl was closely linked to Athena, goddess of wisdom, and traditionally regarded as her companion. Greek coins of the period reflected this, adopting the figure of the owl. In turn, the coins themselves became known as ‘owls’.
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.
