Gold and Silver after a great collapse will be worth nothing. Food, Ammo, guns, secluded land will be in demand. No one will sell any of those to get gold and silver.
Living itself will be day to day.
No one will sell any of those to get gold and silver.
But we will need barter. What if you don’t need guns, seeds or toilet paper but you want a piece of farm equipment? Gold and silver will never loose its value.
