Polish złoty
The value of one red złoty in terms of accounting złotys increased in time, while at the same time the amount of silver found in the grosz decreased. for example, in the 16th century the red złoty's value rose from the initial 30 grosze to almost twice that in just a few decades; in the mid-17th century it was worth six accounting Polish złoty (180 groszy), while in late 18th century, one red złoty was worth about 18 Polish accounting złoty (or 540 groszy).
