The Thaler was the currency of the Electorate, later Kingdom of Hanover until 1857. Until 1834, it was equal to three quarters of a Conventionsthaler and was subdivided into 36 Mariengroschen, each of 8 Pfennig.
Between 1807 and 1813, the Westphalian Thaler (equal to the Hannovarian Thaler) and the Westphalian Frank circulated in Hannover.
In 1834, the Thaler was slightly reduced in silver content to make it equal to the Prussian Thaler. The Thaler was replaced at par in 1857 by the Hannovarian Vereinsthaler.
