Question about gold + abilities

[Xervis]

Hey all, I did a search around both the AP and CW forums and did find anything about this.

I'm using the Folding Bag artifact and it says that it gives '+10% additional gold gained in battle'. Does that mean the gold I gain after battle is over? I also have the Shtopir, but that one clearly says +7% after battle, so I'm confused.

I know there are other items that aren't clear on their meaning but I have forgotten which ones they are at the moment ><
