The Thaler was the currency of the two Duchies, later Grand Duchies, of Mecklenburg-Schwerin and Mecklenburg-Strelitz until 1857. It was replaced the Mecklenburg Vereinsthaler at par. From 1848, it was equal to the Prussian Thaler.
The thaler was subdivided into 48 Schillinge, each of 12 Pfenninge.
