What happened to the German mark after the war?

Answer 1

There was, once again, severe inflation in Germany. The Reichsmark was often not accepted and for many purposes cigarettes were used ... In June 1948 the Reichsmark (RM) was replaced by a new currency, the Deutsche Mark (DM), in the three Western Zones of occupation. RM were converted into DM at the rate of 10:1 on balances up to RM5,000 and 13.5:1 above that.

Answer 2

After World War II, the German mark went through various changes. Initially, it was reissued in 1948 as a new currency to replace the heavily devalued Reichsmark. In 1990, after the reunification of East and West Germany, the German mark became the official currency of the unified country. However, in 2002, it was replaced by the euro as Germany adopted the common currency used by many European countries.
