Szóstak / 6 Groszy - Karol X Gustaw Swedish Occupation

One interesting fact about this coin is that it was minted during the Swedish occupation of Poland in the 17th century, specifically in the city of Elbing (now Elbląg), which was under Swedish control from 1626 to 1659. The coin features an image of King Charles X Gustav of Sweden on one side and the Polish coat of arms on the other. This coin is a rare example of a coin minted during a foreign occupation, and its existence serves as a reminder of the complex history of Poland and its interactions with neighboring countries.
