what is the name of the currency used in the european union
List of currencies in Europe A currency is a medium of exchange, such as money, banknotes, and coins.[2] In Europe, the most commonly used currency is the euro; any country entering the European Union (EU) is expected to join the eurozone[3] when they meet the five convergence criteria.[4] Denmark is the only EU member which has been granted an exemption from using the euro,[3] Sweden has also not adopted the Euro, although unlike Denmark, it has not formally opted out, instead, fails to meet the ERM II (Exchange Rate Mechanism) which results in the non-use of the Euro.[5][6] For countries which hope to join the eurozone, there are five guidelines that need to be followed, grouped in the Maastricht criteria.[3]
10 euro note The changeover period during which the former currencies' notes and coins were exchanged for those of the euro lasted about two months, going from 1 January 2002 until 28 February 2002. The official date on which the national currencies ceased to be legal tender varied from member state to member state.[3] The earliest date was in Germany, where the mark officially ceased to be legal tender on 31 December 2001, though the exchange period lasted for two months more. Even after the old currencies ceased to be legal tender, they continued to be accepted by national central banks for periods ranging from ten years to forever.[3][14]
Deutsche Mark The Deutsche Mark (German: [ˈdɔʏtʃə ˈmaɐ̯k] ( listen), "German mark"), abbreviated "DM" or  "D-Mark" (help·info), was the official currency of West Germany from 1948 until 1990 and later the unified Germany from 1990 until 2002. It was first issued under Allied occupation in 1948 to replace the Reichsmark, and served as the Federal Republic of Germany's official currency from its founding the following year until the adoption of the euro. In English, but not in German, it is commonly called the "Deutschmark" (/ˈdɔɪtʃmɑːrk/).
United States dollar The United States dollar (sign: $; code: USD; also abbreviated US$ and referred to as the dollar, U.S. dollar, or American dollar) is the official currency of the United States and its insular territories per the United States Constitution. For most practical purposes, it is divided into 100 smaller cent (¢) units, but officially it can be divided into 1000 mills (₥). The circulating paper money consists of Federal Reserve Notes that are denominated in United States dollars (12 U.S.C. § 418).
