Gold and Silver for trade

[Two Moon]

I'm trading about a half a ton of gold and silver for the best offer that comes up. If you want it, show me something worth about that much
From the region of The Wolf Lands

[Insel des Mondes]

We can give you the same amount of emeralds, rubies, aquamarines, and/or diamonds.
Your pick.

I'm willing to offer a fourth of a ton of Uranium for the silver only
