Prussian thaler

The Thaler (sometimes Reichsthaler) was the currency of Prussia until 1857. In the 18th century, it was distinct from other north German Reichsthaler in that it contained 1/14 of a Cologne mark of silver, rather than 3/40. Until 1821, it was subdivided in Brandenburg into 24 Groschen, each of 12 Pfennige. In Prussia proper, it was subdivided into 3 Gulden, each of 30 Groschen or 90 Schilling.

Prussia's currency was unified in 1821, with the Thaler subdivided into 30 Silbergroschen, each of 12 Pfenninge.

In 1857, the Prussian Thaler was replaced by the Vereinsthaler, having become the standard across much of Germany.
