The rigsdaler was the name of several currencies used in Denmark until 1875. The similarly named Reichsthaler, riksdaler and rijksdaalder were used in Germany and Austria-Hungary, Sweden and the Netherlands, respectively. These currencies were often Anglicized as rix-dollar or rixdollar.
The Danish currency system established in 1625 consisted of 12 penning = 1 skilling, 16 skilling = 1 mark, 6 mark = 1 rigsdaler and 8 mark = 1 krone. From 1713, two separate systems coexisted, courant and species, with courant being a debased currency also used for banknote issue. The rigsdaler species contained 4⁄37 of a Cologne mark of fine silver (i.e., 9 1⁄4 rigsdaler species equalled one Cologne mark).
In 1813, following a financial crisis, a new currency system was introduced, based on the rigsbankdaler. For six rigsdaler in old banknotes, a new one rigsbankdaler note was exchanged. The rigsbankdaler This was divided into 96 rigsbank skilling and was equal to half a rigsdaler species or 6 rigsdaler courant.
