The German mark was the official currency of Germany from 1948 until 2002, when it was replaced by the euro. It was introduced in West Germany after World War II to stabilize the economy and curb inflation. The mark was known for its strength and reliability, becoming a key currency in Europe. The currency was subdivided into 100 pfennig. Over the years, the German mark underwent several changes in design and security features, reflecting Germany's economic growth. The transition to the euro marked a significant shift in European monetary policy, as many countries adopted a single currency for easier trade and travel.
