2 euro coins (€2) are made of two alloys: the inner part of nickel brass, the outer part of copper-nickel. All coins have a common reverse side and country-specific national sides. The coin has been used since 2002, with the present common side design dating from 2007.

The €2 coin is the coin subject to legal-tendercommemorative issues and hence there is a large number of national sides, including two issues of identical commemorative sides by all eurozone members.

The coin dates from 2002, when euro coins and banknotes were introduced in the 12 member eurozone and its related territories. The common side was designed by Luc Luycx, a Belgian artist who won a Europe-wide competition to design the new coins. The designs of the one and two-euro coins were intended to show the European Union (EU) as a whole with the then 15 countries more closely joined together than on the 10 to 50-cent coins (the 1-cent to 5-cent coins showed the EU as one, though intending to show its place in the world).

The national sides, then 15 (eurozone + Monaco, San Marino and the Vatican who could mint their own) were each designed according to national competitions, though to specifications which applied to all coins such as the requirement of including twelve stars (see euro coins for more). National designs were not allowed to change until the end of 2008, unless a monarch (whose portrait usually appears on the coins) dies or abdicates. This happened in Monaco and the Vatican City resulting in three new designs in circulation (the Vatican had an interim design until the new Pope was selected). National designs have seen some changes due to new rule stating that national designs should include the name of the issuing country (Finland and Belgium both do not show their name, and hence have made minor changes).

Grace Patricia Kelly (November 12, 1929 – September 14, 1982) was an American actress who, in April 1956, married Rainier III, Prince of Monaco, to become Princess consort of Monaco, styled as Her Serene Highness The Princess of Monaco, and commonly referred to as Princess Grace.

After embarking on an acting career in 1950, at the age of 20, Grace Kelly appeared in New York City theatrical productions as well as in more than forty episodes of live drama productions broadcast during the early 1950s Golden Age of Television. In October 1953, with the release of Mogambo, she became a movie star, a status confirmed in 1954 with a Golden Globe Award and Academy Award nomination as well as leading roles in five films, including The Country Girl, in which she gave a deglamorized, Academy Award-winning performance. She retired from acting at 26 to enter upon her duties in Monaco. She and Prince Rainier had three children: Caroline, Albert, and Stéphanie. She also retained her American roots, maintaining dual US and Monégasque citizenships.
