How about this? I can't seem to find the pile of coins icon, and the commerce-coin and gold-ingot-resource are not very recognizable at all against the shield.

That seems far too large for the shield. The black border stands out, yes, but now it looks like it doesn't fit there at all.
I think that maybe a gold ring would work better than a solid coin.
Well, if you really will to change it, maybe the shield could be just a bit smaller as it is too much in the face of the guy in my opinion. But if you don't change anything it's still good
