If the American economy collapsed, gold would get you nothing. A fifth of cheap vodka would be worth more as would any type of food.
Swap / Trade for ammo?
My husband has a side job. He takes silver as payment. Most of his customers know this. You’d be surprised the people he’s woken up doing this. We have a network of people we can “trade” with. He has built this for years.
Someone will always be looking for old valuables, but most will trade ammo for a can of string beans, vodka,moonshine, cigarettes, rifles, propane, gas, diesel, your wife or daughters for 30 minutes. It will all be worth more than gold.
