Currency

Currency is measured via Silver coins, cut into various sizes.
They're known by varying names across different nations, but for the sake of the system the tiers go like this.
1 Gold Ducat (GD) = 4 Silver Ducats ($96)
1 Silver Ducat (SD) = 4 Silver Shillings ($24)
1 Silver Shilling (SS) = 9kg Wheat Grain, $6 USD (Roughly)
