Well, it depends on what...
textbook you are reading I suppose. They still got what ever purchasing power the papaer money had. The Swiss just did the same thing by devaluing the Franc (in fact they all but abandonded gold in '71 too) the Argentinians did it in devaluing their currency just a few years ago. That's how it works-countries do what is best for them, all things considered. If taking a little heat over making funny money acheives the goal then so be it. The gold standard is the hobby horse of some not all.
