The ½ million mark coin is a notgeld piece that was issued by the Free and Hanseatic City of Hamburg in August 1923, during its period as a city-state of the Weimar Republic and in the midst of extreme hyperinflation. It was produced at the Hamburg Mint, as can be identified from the "J" mark on the obverse. The piece had a value equivalent to 500,000.00 mark prior to its demonetization, but as a token coin exclusive to Hamburg, it could only be used as payment there.
The coin is composed of aluminum and has a mass of 2.01 grams and a diameter of 28 millimeters. It has medallic alignment and a plain edge, and like most coins, is round in shape. Displayed in the middle of the obverse is the coat of arms of Hamburg – which consists of an escutcheon featuring a castle with three towers, supported by two lions standing atop a platform and surmounted by a helmet, six banners, and three peacock (Pavo) feathers. The German legend "FREIE UND HANSESTADT HAMBURG" is inscribed along the rim of the coin, commencing in an upward direction at the left periphery, curving downward at the top of the piece, and concluding at the right side of the obverse. At the very bottom of the coin, underneath the illustration of the arms, is the "J" mint mark of Hamburg in small print. Engraved in the center of the reverse on three lines is the value "½ MILLION MARK", the font on each line getting smaller further down the coin. The word "NOTGELD" is printed along the upper rim of the reverse, essentially signifying the piece as emergency money, while the date "AUGUST 1923" is included along the coin's bottom periphery. "NOTGELD" is flanked to the left and right by a five-pointed star, and another such star is located between the word "MARK" in the value and the date.
