What is polish crowns?

Polish Crowns were a series of gold, silver, and copper coins that were minted and used in Poland from the late 14th century until the mid-17th century. The name of the coin comes from the depiction of the Polish coat of arms on one side, which featured an eagle with a crown above its head. The coins were used as a means of exchange for goods and services, and their value was based on the weight of the precious metal used to mint them. Over time, the Polish Crown was also used as a unit of currency, with one Crown representing a certain amount of goods or services. The denomination of the Polish Crown varied over time and across different regions of Poland, and the coins themselves often featured different designs and inscriptions. Despite their eventual disappearance from circulation, the Polish Crown remains an important symbol of Poland's economic and cultural history.
