Since 2006, Germany has issued a special 2 Euro coin from a Bundesland (province) every year, depicting an important object from that region. The theme of the 2018 German 2 Euro is the state of Berlin.
Berlin is the capital and largest city of Germany by both area and population. One of Germany's sixteen constituent states, Berlin is surrounded by the State of Brandenburg and is contiguous with Potsdam, Brandenburg's capital. The obverse of the coin features the Charlottenburg Palace in Berlin.
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.
