[Fallout] I got a fair amount of Nuka Cola bottle caps but they're all creased and a little rusty. Will the caravans accept them? I need my Cram.

Yeah, sure. Not every cap comes from a pristine, perfectly preserved bottle of Nuka fresh from the Vendo-O-Tron. They get traded around, carried around the wastes, dropped, and generally beaten up. As long as the person you're trading with *believes* it's a genuine cap, it's a genuine cap. 

I've heard back in the Pre-War days they used paper money. Paper money! Now THAT'S something that would be hard to take care of. It's not nice and hardy like a cap.
