8 Heller

Cologne's civic coinage of this period existed in permanent tension with the Archbishop's mint rights — the city had fought for decades to maintain independent striking privileges, and these small silver issues were among the practical expressions of that autonomy. The Heller denomination itself had roots in the Rhenish monetary system stretching back to the thirteenth century.

The Noss reference covers multiple die varieties across this short run, suggesting fairly active production despite the modest denomination.
