in the Prussian system, by subdividing the thaler into 30 Page 204 instead of as previously 24 groschen, the former being distinguished from the latter by the title of silver groschen. To this Prussian or 14-thaler system Saxony acceded, as did also, in 1848, Mecklenburg and Oldenburg, with many minor differences of detail,—Saxony, for example, dividing the silver groschen into 10 pfennige; Mecklenburg dividing the thaler into 48 schillings of 12 pfennige each; and Oldenburg dividing it into 72 grotens of 5 schwarens each. The gold coin was supplied by the Prussian and Hanoverian 5 and 10-thaler pieces, the Friedrichs d'or, a favourite trade coin even in South Germany, and by Spanish pistoles circulating at an equivalence of 4 6-livre thalers.
The confusion of these various German systems was further increased by the uncertainty and difference which had come to prevail in the unit of weight. In Austria alone there were 2 marks in use, the Vienna mark (= 288.644 grs.), and the Cologne mark (= 243.870 grs.). While in North Germany, and subsequently in the south-west, the Prussian mark (= 233.855 grs.) prevailed. It was as the outcome of a desire to remedy at once the evil condition and confusion of the currency, and the uncertainty as to weight standard, which led to the conference of Munich on 25th August 1837. At that conference, Bavaria, Würtemberg, Baden, Hesse, Darmstadt, and the Free State of Frankfort, adopted the 24 1⁄2-gulden standard as the standard for their several states.
