There is no number of 1962 dollars that could buy you an electric car, HPV vaccine, or Nintendo DS, which means they're worthless if you want to buy those things.
(Since you can't time travel from 1962 to a point where those existed. If you just waited for them, then presumably you've kept them in an interest-bearing account in the meantime, and so the value of the dollar doesn't apply.)
