 Since January 2001 the country decided to take this currency as a sole legal tender, because a sufficient amount of Deutsche Mark were in circulation, and for this reason there was no need to use the Dinar as the national currency.On 1 January 2002 the euro notes and coins were officially introduced into circulation in many European countries, including Germany, where the Deutsche Mark used to be an official currency.Thus the Deutsche Mark ceased to be legal tender immediately upon the adoption of the euro.
