The coins are composed of
copper-covered
steel, with a diameter of 21.25 mm, a 1.67 mm thickness and a mass of 3.92 grams. The coins' edges are smooth. Coincidentally, the dimensions (though not the mass or composition) are nearly identical to those of
Canadian and
United States 5-cent coins. The coins have been used from 2002, though some are dated 1999 which is the year the
euro was created as a currency, but not put into general circulation.
Reverse (common) side The reverse was designed by Luc Luycx and displays a globe in the bottom right. The (then 15) members of the EU are lightly highlighted and the northern part of
Africa and the western part of
Asia (including the
Middle East) are shown. Six fine lines cut diagonally behind the globe from each side of the coin and have twelve stars at their ends (reflective of the
flag of Europe). To the top left is a large number 5 followed, in smaller text, by the words "Euro Cent". The designer's initials, LL, appear to the right of the globe. Starting in 2017 coins from individual member states have started adjusting their common side design to a new version, identified by smaller and more rounded numeral "5" and longer lines outside of the stars at the coin's circumference.
Obverse (national) sides The obverse side of the coin depends on the issuing country. All have to include the name or an abbreviation of the issuing country. The national side of circulation coins shall bear a circle of 12 stars that shall fully surround the national design, including the year mark and the indication of the issuing Member State’s name. The side cannot repeat the denomination of the coin unless the issuing country uses an alphabet other than
Latin. Currently,
Greece,
Cyprus and
Bulgaria are the only such countries. Greece engraves "5 ΛΕΠΤΑ" (5 lepta) on its coins and Bulgaria engraves "СТОТИНКИ" (stotinki).
Austria ignores this rule, engraving "FÜNF EURO CENT" on its coins, hence will have to change its design to comply this rule.
Belgium,
Finland,
France,
the Netherlands and
Spain minted coins dated 1999, 2000 and 2001 although these entered circulation in 2002.
Monaco minted coins dated 2001 although these entered circulation in 2002 too.
Potential designs Austria, Germany and Greece will also at some point need to update their designs to comply with guidelines stating they must include the issuing state's name or initials, and not repeat the denomination of the coin (Austria only). On the other hand, Slovenia and Greece have to comply with the star rule. In addition, there are several EU states that have not yet adopted the euro. Some of them have already agreed upon their coin designs; however, it is not known if or when they will adopt the currency, and hence these are not yet minted. See
enlargement of the Eurozone for expected entry dates of these countries. ==Nicknames==
