This mod adds coins and paper currency worth 5-10-20-50 and 100 coins.
And it adds a /money command to quickly display all your money.
Also, you can burn paper currency, if you want to.
You can configure the currency name in config.lua.
Currently, there aren't any way to craft any of the mod's items,
as server admins might want to control the economy on their own.
