3 Groschen Siege coinage; countermarked

One interesting fact about the 3 Groschen coin from the City of Danzig (Polish States) is that it was countermarked, which means that a new stamp or mark was added to the coin after it was originally minted. This practice was common during times of war or economic crisis, as it allowed authorities to revalue or reissue coins that were already in circulation. In this case, the countermark on the 3 Groschen coin may have been added to indicate that it was issued during a time of siege or economic hardship, and it could have been used as a way to control the flow of currency or to raise funds for military or other purposes.
