I apologize if this has been asked before, I've searched for it but I haven't found anything.
Anyway, I have a question regarding income from precious metal. Right now I'm playing as the California Republic and I have one precious metal producing province (Mariposa). When I select the province and look at the RGO info it says it produces 9.222 units of precious metal for a total value of 69.163 pounds. However, when I go to my budget tab I only get 13.8 pounds from gold income. Isn't all of the income from gold supposed to go straight to my treasury? Or is it based off of tax/administrative efficiency?
