What do you think would be the main post-apocalyptic currency?

I would say that the money we have now could be used. But because we wouldn't have any means of producing more money (through printing and such), then the coins/notes/etc that were left would be far more valuable. For instance, a penny might not get you much now, but if there was no way to make more pennies then you might find you can suddenly exchange it for something that would have once cost much more, like a can of soda for instance (assuming there's any of those left).
