The Hamburg Mark Banco was a form of bank money created by the Hamburger Bank in 1619 in order to provide a more reliable medium of exchange in the midst of the monetary chaos of the Kipper und Wipperzeit.
While the Reichsthaler was originally defined as 25.984 grams (1⁄9th a Cologne mark, or 233.856 g) fine silver, the Bank of Amsterdam's lower standard for the Dutch rijksdaalder of 25.4 g prevailed for the next two centuries.
[3] A mostly similar currency system was used in Denmark, Norway and Schleswig-Holstein, but with a slightly lower thaler courant worth 4⁄5 the Reichsthaler specie, so that the latter equalled 60 schillings courant (or 120 skillings Danske in Denmark and Norway).
Lübeck ceased minting coins after 1801 but continued to use the same currency system as Hamburg until German unification.
By the time of the introduction of the German mark in 1873, Hamburg currency constituted 61% of the coins in circulation in Lübeck.
