Some believe that it was commissioned by the Mint of Bydgoszcz as a gift for the king or for someone close to him.

Polish forces, together with Cossacks, defeated the Turks after 26 days of fighting near Chocim in northern Bessarabia.

The sultan had planned to conquer Ukraine, Poland, and eventually all of central Europe.
