Reichsmark
The Reichsmark (German: [ˈʁaɪçsˌmaʁk] ; sign: ℛ︁ℳ︁; abbreviation: RM) was the currency of Germany from 1924 until the fall of Nazi Germany in 1945, and in the American, British and French occupied zones of Germany, until 20 June 1948. The Reichsmark was then replaced by the Deutsche Mark, to become the currency of West Germany and then all of Germany after the 1990 reunification.
