During this period, there were several monetary reforms in the PLC, to simplify this I will take data from 1628-1640.
Ducat - Gold coin.
Thaler - A large silver coin, 2 thalers are 1 ducat.
Grosz (Penny) - A small silver coin. 90 pennys is 1 thaler.
For example...
The carpenter earned 24 pennys a day, which made 648 pennys a month or about 7 thalers. However, ducats and thalers were used mostly by nobility and merchants.
