The North German thaler was the currency of the Landgravate, then Electorate of Hesse-Kassel (or Hesse-Cassel) until 1858. Until 1807, the Thaler was subdivided into 32 Albus, each of 12 Heller. It was worth 3⁄4th a Conventionsthaler from 1754 to 1841. Between 1807 and 1813, the Westphalian Thaler and Westphalian Frank circulated in Hesse-Kassel. The Thaler was replaced at par by the Vereinsthaler.
