Well "unsearched" rolls of wheat pennies sell for like 3 dollars, why not hoard rolls today and then in 40 years sell them for a premium, if you did this in the 1950s you would of made some profit, although perhaps it would of been beneficial to put it in the bank at that point, however I agree that the american dollar is decreasing in value, and will continue to do so, making any material investment probably a better idea. I agree that we are eventually going to have to cancel out the debt, as we are never going to have pay it off. By then it will be Americans taking a wheel barrow to the grocery store of USD to buy a loaf of bread lol
