Okay, as long as we're wheeling and dealing here, I'll make a counter-offer for everybody wise enough to realize that paper money is inherently worthless, and gold is the only real money (with silver an acceptable stand-in). I'll take your worthless scrip, in the form of current $100 bills, and trade you weight for weight Constitutional gold money, either circulated pre-1933 or contemporary commemoratives and bullion, your choice. That should work out to around $3000 per ounce, barely above the "value" people pretend paper dollars carry today. For Constitutional 90% silver, I'll even take $1 bills. Weight for weight. If you really believe paper money is worthless, what's stopping you?
I never said paper money is worthless. If you take your silver dollar coin or gold coin to a store or bank they'll give you face value. Just like paper money. But I'll gladly trade face value paper (plus some) for face value PM coin. I don't do weight. Weight isn't used in stores or banks.
There are only 2 economic extremes to be concerned about. In deflation, cash (greenbacks & coins) is king. In hyperinflation PMs are. Therefore, to cover both ends, accumulate junk 90% silver Rosies and GW quarters. Their visual appearances have not changed in generations. They will still be recognized as cash by even the 7-11 clerk during deflationary conditions (vs. a gold saint). Yet, with hyperinflation, their silver content will help you buy half the store. Under difficult times, people will only buy/sell/trade with what they understand and junk Ag is the way to go. The more likely to occur moderate conditions in between these extremes will still respect all forms of silver and gold. Therefore, you cannot lose with them, esp. the common 90% silver.
No. In hyperinflation, it's the value of the dollar that would drop, not the value of "everything but PMs". That silver dime that famously bought you a loaf of bread in 1964, "and still does" (although it's a downscale loaf compared to 2011-2012), would still buy you about one loaf of bread -- even if the price marked on the shelf went to $9,999 per loaf. But I don't think even the most ardent preppers are expecting to get ten loaves for their silver dime.
