So there's been some questions on currency in the world. I'm gonna add this to the world info stuff too, but here's the gist on money in the rp:
There's a standardized metal currency used in trade between the nations. Coppers and silvers; which represent pennies and dollars. Since there's so much scarcity, 12 coppers could buy you a nice meal, and five silvers might buy you a standard gun.
Gold is also a valuable currency, with coins being worth a lot of silvers; and a gold bar being an extremely precious resource.
