Since 2006, Germany has issued a special 2 Euro coin from a Bundesland (province) every year, depicting an important object from that region. This is a special case in the series though; the year in which the coin for a specific state is issued coincides with that state's Presidency of the Bundesrat. In 2018, Daniel Günther, the Minister President of Schleswig-Holstein, became the President of the Bundesrat for a one-year term. As a Schleswig-Holstein coin had already been minted in 2006, it was decided to delay the release of the following three states' coins by a year. Instead of honouring a state in 2019, the minted coin commemorates 70 years since the constitution of the German Federal Council or Bundesrat in German.
The German Bundesrat is a legislative body that represents the sixteen Länder (federated states) of Germany at the federal level (German: Bundesebene). The Bundesrat meets at the former Prussian House of Lords in Berlin - which is depicted on the €2 coin. The Bundesrat participates in legislation, alongside the Bundestag consisting of directly elected representatives of the German people. Laws that affect state powers, and all constitutional changes, need the consent of both houses. For its somewhat similar function, the Bundesrat is sometimes (controversially) described as an upper house of parliament along the lines of the United States Senate, the Canadian Senate, and the British House of Lords.
Germany has five mints which strike circulation coins; they are distinguished by their mint marks - A for Berlin, D for Munich, F for Stuttgart, G for Karlsruhe and J for Hamburg. The set contains five coins with the same design, each struck by a different mint and with its respective mint mark. The quality is proof, which in German is called Spiegelglanz.
