Grzywna

The "grzywna" was a measure of weight, mainly for silver, commonly used throughout medieval central and eastern Europe, particularly in the Kingdom of Poland and Kingdom of Bohemia (Czech: hřivna).

Grzywna was also a unit of measure of a unit of exchange, and as such used as money in the 10th–15th centuries. Silver ingots acted as commodity money before the widespread use of minted coins. more
