Dukat gdański - Władysław IV Waza Gdańsk mint

Gdańsk held a rare privilege among Polish-Lithuanian Commonwealth cities: the right to strike its own gold coinage, a concession tied directly to the city's status as a semi-autonomous trading hub controlling Baltic grain exports. The municipal ducat series under Władysław IV spans nearly two decades of his reign, during which the king repeatedly needed Gdańsk's financial cooperation — particularly during the costly conflicts with Sweden and the Ottoman threat pressing from the south. The city leveraged that need carefully.

The multiple Kop references reflect distinct annual die varieties across the run, not a single type. Collectors who treat this as one coin miss the chronological story embedded in the series.
