Hesse-Kassel thaler  The 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 three quarters of a Conventionsthaler. Between 1807 and 1813, the Westphalian Thaler and Westphalian Frank circulated in Hesse-Kassel. The Thaler and Heller were reintroduced in 1813, but without the Albus (the last coins denominated in Albus were issued in 1782). Thus, 384 Heller = 1 Thaler. In 1819, the Thaler was set equal to the Prussian Thaler. In 1841, a new currency system was introduced, dividing the Thaler into 30 "Silbergroschen", each of 12 Heller. The Thaler was replaced at par by the Vereinsthaler.
