Hyper inflation will wipe out your cash at hand plus people rightfully panic into gold and silver during a hyper inflation. But thankfully hyper inflations are very rare in history. One of Glenn Beck's guests made that point
Believe it or not the US Treasury has always delivered on T Bills...even during the Civil War. If for no other reason that screwing T Bill holders makes it more difficult to borrow in the future
Your green cash Federal Reserve Notes (FRNs) are also jealousy guarded as far as their integrity. They are legal tender "to settle all debts both public and private" and the USG will make sure it stays this way
We have deflation now same as in the 1930's and green cash under your mattress did great back then compared to being victimized by a bank failure, bank runs etc. Any inflation we get a few years from now will be tolerable--less that 10% and you can deal with your green cash then because it will indeed be losing value
But right now any green cash FRNs you have are gaining in value day by day due to the unusual deflation we have right now so no sweat. The biggest threat to FRNs is a new currency. There might be limits on how much old money you can exchange for new money. But the USA is so anarchic these days I don't think the USG can make such limits stick. A black market will arise among immigrants and others
Gold can be very hard to sell during "the chaos". Home invasion men will be scoping out gold exchanges and looking for you and me. Silver is better and gold wedding rings too. You don't look like a big shot with these items
Gold is what you want to preserve until after "the chaos" and the rebuilding phase starts with more law and order in place
Excellent advice. Thanks.
