Heller

Troppau (now Opava, Czech Republic) occupied an awkward political position throughout this period — nominally a Silesian duchy under Piast and later Habsburg influence, yet functionally semi-autonomous in its municipal coinage rights. The heller was the workhorse denomination of everyday trade in the region, and Troppau's extended run of this type across five decades reflects sustained commercial activity rather than ceremonial minting. The Kop#6360 attribution places this squarely among the bracteate-influenced small silver issues documented for Silesian civic mints of the late medieval period.
