also called Timpf, from the name of the mintmaster, Andreas Tympf. A base silver Gulden of Poland, first issued in 1663. These coins were extensively struck under the Electors of Saxony as Kings of Poland, and also by the Electors of Brandenburg for Danzig, Konigsberg, and the Polish and Lithuanian provinces. They bear on one side a portrait of the ruler, and on the other the figure 18, i.e., eighteen Groschen. From this circum- stance they are sometimes referred to as Achtzehngroscher.
In Russia, the same coin is also called Tschech, and here it was issued at the be- ginning of the eighteenth century, of the value of twelve Kopecks. There is a half Tympf of the same period.
