Danzig gulden

The Danzig gulden was the currency of the Free City of Danzig (present-day Gdańsk, Poland) between 1923 and 1939. Inflation in Danzig during 1922 had spiralled out of control, and the city abandoned the German Papiermark in favour of the Danzig gulden the following year. The issuance of the new gulden was overseen by the Bank of Danzig, established in early 1924. The obverse of each note shows the city's coat of arms on the left and an important local architectural structure in the centre. This ten-gulden banknote, issued in 1930, bears an illustration of the Artus Court, previously a meeting place of merchants and a centre of social life, and now part of the Gdańsk History Museum.
