Average Joe on the street:
"I don't believe physical money with intrinsic value (silver, gold coins) will ever come back. If WW3 happens then what will be back is barter. In a post-apocalyptic world, silver and gold matter much less than clean water or better a way to make it, food, guns and bullets, etc."Other person:
"So you don't own any gold or silver?"Average Joe:
"Nope."Other person:
"So I'm assuming that by your previous statement then that you've at least stocked up on clean water, food, guns, and bullets in case WW3 did happen?"Average Joe:
"Well, no, not really. I live in a one bedroom house in the city."Lol, irony.

silver and gold would have value for a 5-10 day period when people believed it was just a blip. if it ain't a blip then they are pieces of metal that take up space in your pocket and nothing else. maybe they'd be worth something a couple of generations down the line if the world was ever rebuilt.
