Physical gold/silver is the only true and trusted market. When things get out of whack with the paper markets, physical metals will be the true price (maybe with a big premium above the paper price). Or physical will not be available at all. Supply and demand always holds true with physical metal. Not so much with paper metal. Supply can be fraudulently manipulated with paper.
That's what I'm kinda curious about. All the PM physical dealers I've met buy and sell based off the market spot price. I guess if they can't get a hold of the physical metal in a currency crisis, then the price (in USD) would rise rapidly in that local market. Perhaps at that point, I would be able to sell the metal for a hefty profit in USD, in order to buy food/gas. But then there are capital gains taxes to pay. As someone else suggested, I would be better off investing in self-sustainment capabilities now, and only buying PMs after that.
