Heller

Toszek (Tost in German) was a small Silesian town that passed through a succession of Piast dukes and Bohemian overlords during the fifteenth century, a period of chronic political fragmentation that pushed many minor Silesian lordships to strike their own small silver. The heller denomination itself derived from Schwäbisch Hall, and by the time issues like this one were circulating in Upper Silesia, the type had been thoroughly regionalized — weight standards drifting considerably from the original Rhenish model.

Kop. 8747 places this firmly within the documented Silesian municipal issues, though the precise decade of striking within the century remains unresolved.
