Conventionsthaler

The Leipzig standard defined the North German thaler currency unit at 3⁄4 the Reichsthaler specie of 25.984 g, or 19.488 g fine silver.

However, this parity did not exist with the inferior south German lower denomination coins where the Conventionsthaler was worth two gulden and 12 kreuzer.

The Conventionsthaler was introduced as the successor to the Reichsthaler on 7 November 1750 in the Austrian crown lands.

The Conventionsthaler succeeded the Reichsthaler specie (containing 25.984 g fine silver) as the standard coin in most of the Holy Roman Empire, with a variety of subdivisions being used: Thus, converted to the theoretical (counting) Reichstaler of the old German Empire, which was worth 24 groschen, the Conventionsthaler corresponded to a 13+1⁄3-thaler standard in relation to the Cologne mark.

Meanwhile, the Prussian 'new' Reichstaler, minted in real terms from 1750 onwards, corresponded to a 14-thaler standard developed by Johann Philipp Graumann.
