Dwugrosz - Jan II Kazimierz Waza Wschowa mint

The Wschowa mint operated under lease arrangements common to the Commonwealth's decentralized monetary administration, with private contractors responsible for both production costs and profit — a system that incentivized output but created chronic quality control problems. Dwugrosze from this facility across the 1650–1654 window show considerable variation in die workmanship, which accounts for the spread of Kopicki references rather than a single type.

These years coincided with the opening phases of the Deluge — the catastrophic Swedish and Russian invasions that would devastate the Commonwealth's population and economy. Coin production continued under severe fiscal pressure, feeding military expenditure that ultimately proved insufficient.
