12 Pfennig

Werl, a Westphalian town under the jurisdiction of the Archbishop of Cologne, issued copper small-denomination coins during the seventeenth century as emergency municipal coinage — Notmünzen produced when the disruption of the Thirty Years' War fractured normal coin supply across the region. The 12 Pfennig denomination sits awkwardly in the local reckoning, suggesting it was calibrated to fill a specific transactional gap rather than conform to any imperial standard.
