There are eight euro coin denominations, ranging from one cent to two euros (the euro is divided into a hundred cents). The coins first came into use in 1999. They have a common reverse, portraying a map of Europe, but each country in the eurozone has its own design on the obverse, which means that each coin has a variety of different designs in circulation at once. Four European micro states that are not members of the European Union (Andorra, Monaco, San Marino, and the Vatican City) use the euro as their currency and also have the right to mint coins with their own designs on the obverse side.
The coins, and various commemorative coins, are minted at numerous national mints across the European Union to strict national quotas. Obverse designs are chosen nationally, while the reverse and the currency as a whole is managed by the European Central Bank (ECB).
There are eight different denominations of euro coins: 1c, 2c, 5c, 10c, 20c, 50c, €1 and €2. The 1c, 2c and 5c coins show Europe in relation to Asia and Africa in the world. The remaining coins show the EU before its enlargement in May 2004 if minted before 1 January 2007, or a geographical map of Europe if minted after. Coins from Italy, San Marino, the Vatican City, Austria and Portugal show the geographical map if minted in 2008 or later.
As of 2015 there are 23 countries issuing coins with their own national sides, making it 184 different euro coins, not counting annual differences or commemorative coins.
