Grosz Público Deposited
(Plural Groszy or Grosze.) The Polish name for the Gros (q.v.). The earliest issues under King Wenceslaus II (1278-1305) were of silver and read GROSSI: PRAGENSES ; their popular name being Prager Groschen.
Later the Groszy were made of copper and thirty were equal to a Gulden. By an imperial ukase of 1841 the coinage ceased and the Russian Kopecks took their place.
