A nickel is worth 5 cents

The technical data and packaging of the euro coins

Despite different backs: coins are valid in all EMU countries

The front of the euro coins is uniform across Europe and shows the value of the coins in large digits, the reverse of the coins is designed according to each country's own national motifs. However, this has no effect on the use of the common currency as a means of payment. Regardless of the design of the national reverse, the technical data of the coins are standardized for all euro countries. Material, thickness, weight and edge design are identical. This means that the euro coins can also be recognized by machine in all Member States.

The technical questions of coin production are a matter for the mint directors of the member states of the European Union. The European Commission has done important preparatory work on the question of the technical design of the coins. In doing so, she called in consumer and blind associations as well as representatives of the vending machine industry. The task was to create coins that all Europeans like, that people and machines can distinguish well and that blind people can easily feel.

The result is a very modern and uniform European coin system - user-friendly and forgery-proof. So that the individual coins can be easily distinguished from one another, they have different visual and tactile marks. The coins differ in color, shape and size. To protect against counterfeiting, the coins are made of three layers and the two largest denominations (1 and 2 euros) are combined in two different colors.

Particular emphasis was placed on the coins having a low nickel content, as nickel can cause allergies: the small coins (1, 2 and 5 cents) are nickel-free. They contain a steel core with a copper coating. An alloy from Scandinavia is used for the medium coins (10, 20 and 50 cents). This is called "Nordic gold". These coins are also nickel-free. A special feature: the euro coins of 10, 20 and 50 cents made from the alloy "Nordic gold" are not magnetic.

The decision to use nickel was only made for the 1 and 2 euro coins, as this metal is better suited for printing security features. The allergy risk was reduced by a very high quality alloy.
