The Two Marks coin, abbreviated 2 DM and known in English as 2 German Marks, was a relatively large circulating denomination of the Deutsche Mark (German mark), which was the official currency of West Germany from 1948 until 1990 and later of unified Germany from 1990 until 2002.
The initial design was similar to the 1 Mark coin and was only issued in 1951. It was superseded by a design honouring Max Planck, which was issued between 1957 and 1971.
Those earlier coins were made of CuproNickel and were confusing to vending machines (which mistakenly accepted cheap foreign coins instead of 2 DM), so were demonetized in 1973 and replaced by a new series of coins called the "politicians series" because it depicts portraits of German politicians on the obverse. These coins are three-layered: CuproNickel with a Nickel core, which makes them magnetic unlike the earlier ones.
This type of coins honours Dr. Franz Josef Strauß (1915 - 1988; his surname is spelled Strauss in English), a German politician was defence minister in 1956 in charge of rebuilding the Bundeswehr, chairman of the Bavarian political party CSU from 1961 on and Bavarian minister-president from 1978 to his death.
Other coins of the "politicians series" include:
- Konrad Adenauer, 1969 - 1987
- Theodor Heuss, 1970 - 1987
- Kurt Schumacher, 1979 - 1993
- Ludwig Erhard, 1988 - 2001
- Willy Brandt, 1994 - 2001
Note that the introduction of new designs did not supplant the previous ones; older designs continued to be issued and used in parallel.
The edge inscription was the same throughout the history of the denomination: Einigkeit und Recht und Freiheit, meaning "Unity and Justice and Freedom".
In 1999, the Deutsche Mark was replaced by the Euro; its coins and banknotes remained in circulation, defined in terms of euros, until the introduction of euro notes and coins on 1 January 2002. In preparation for the event, Germany stopped issuing new German Mark coins. Some were struck for the mint sets of the year (in uncirculated and in proof grades), but none were issued into circulation.
All coins of this type were demonetised only one year later, and were not acceptable as payment after 28 February 2002.
