Europhiles can check out the coins from the different member states. For those not familiar with the euro, the notes are all the same, but the coins reflect the country of origin. The Irish euro has a harp on it, the German one an eagle and the Italian euro has the Vitruvian Man. Look also at Greece, Austria and Portugal.
Most are round, but some have holes (Denmark, Norway) and others are have, err, wiggly edges (Libya, Maldives, Myanmar). I can understand why people collect coins as they’re a fascinating insight into each country, often showing not only the history but also the aspiration of the nation.
