Definitley Bottle Caps from Fallout.
In a post apocalyptic wasteland, why would bottle caps become a universally traded item? I can understand why money wouldn't be used any more, but what functional purpose to bottle caps have?
And why would every town, place, travelling salesman, etc, all decide these were what you should use for currency?
It makes no sense. There is no logical argument for why bottle caps would make good currency...
