There is a separate currency called Gold. I noticed this in the item translation file.
The lines involved are:
Gold
High Currency
Royal Kingdom Upper Currency
This is opposed to silver’s set of lines:
Silver
Common Currency
Royal Kingdom
I feel like this is something interesting and should be discussed. What does it mean? Is it a generic 1k silver = 1 gold system? Or, based on the description, some form of “upper class” currency?
Edit: Sike, I’m just dumb. The terms “Gold” and “Coins” are used within the translation files as terms for NXP. Silver is, seemingly, the sole term for in-game currency.
