What is a coin?
Coins are a type of legal tender that are circulated alongside banknotes. Coins can easily be recognised: They carry the national emblem of the country of origin and the value at which they are accepted and circulated for payment. The German Coinage Act (MünzG) of 16 December 1999 regulates coin minting in Germany. It decrees that the Ministry of Finance is responsible for deciding which mint strikes coins and in what quantity. The Bundesbank (German Central Bank) is responsible for putting the coins into circulation.
A commemorative coin is a coin that differs from the usual coins in circulation in its motif, or, occasionally, in its technical specifications. Commemorative coins are produced to mark events or themes that create a sense of identity.
2 euro commemorative coins
Each member of the European Monetary Union may issue up to two 2 euro circulation coins per year with special designs on the reverse. These have the same technical specifications as conventional 2 euro coins and are legal tender across the entire euro area.
Each member of the European Monetary Union decides on the quantity and design of its collector’s coins, which are accepted as legal tender only in the country of origin. Each year, Germany issues several collector’s coins in silver at a nominal value of 20 euros. 100 euro and 25 euro collector’s gold coins have been available since 2002 and 2010, respectively. The first 5 euro polymer coin appeared in 2016. Collector’s coins are produced in "proof" quality, the achievement of which is a difficult technical feat. Proof coins are sold exclusively by the German Sales Agency for Collector's Coins (VfS). Collector’s coins in circulation quality can be obtained from local private and public banks.
