Heller

Liegnitz operated as a semi-autonomous Piast duchy well into the fifteenth century, and its civic coinage reflects the fractured political reality of Silesian territory caught between Bohemian suzerainty and local dynastic ambition. The heller denomination itself originated in the imperial town of Schwäbisch Hall — the name a direct corruption of "Haller" — before spreading across the German-speaking lands as a low-value fiduciary piece that municipal authorities could strike with minimal oversight from higher powers.

At 0.21 g, these pieces were so light that wear and clipping rendered individual coins nearly interchangeable by weight alone.
