He also says they are the easiest type of coin to stockpile since there has only been one version of the nickel since WWII, so no sorting by date necessary.

In addition, he says that if the currency is ever officially devalued and old currency must be traded in for new bills, coins will likely be left alone because of the hassle. So, after the devaluation, you would've instantly made a tidy return on your coins. But really, if you seriously were thinking of that possibility, collecting nickels is a pretty inefficient way to take advantage of that particular situation.

And how many nickels would have to be melted down to pay for a large latte through the value of the metals? Sounds like trying to save up for 30 years of retirement by collecting aluminum cans. It's kind of a neat idea on paper, but very impractical in real life IMHO.
