2 Ducats - Karol X Gustaw Swedish Occupation

Elbing — modern Elbląg in northern Poland — was a Hanseatic trading city that passed repeatedly between Polish and Swedish control during the seventeenth century. Charles X Gustav occupied it as part of the First Northern War, and the city's right to strike its own gold coinage under Swedish occupation was a deliberate political concession, acknowledging Elbing's commercial weight and keeping the merchant class cooperative. These ducats circulated alongside Polish and Swedish issues simultaneously, a numismatic consequence of a city that owed loyalty to whoever held the garrison.

The emission spans six years of occupation, ending when Elbing reverted to Polish sovereignty under the Treaty of Oliwa in 1660.
