ズウォティ
The name "złoty" (sometimes referred to as the florin) was used for a number of different coins, including the 30-grosz coin called the "polski złoty", the "czerwony złoty" ("red złoty") and the "złoty reński" (the Rhine guilder), which were in circulation at the time. However, the value of the Polish złoty dropped over time relative to these foreign coins, and it became a silver coin, with the foreign ducats eventually circulating at approximately 5 złoty.
