Of course not. It will be the same as every other country which has gone through it. A few zeros will be knocked of the end. Or, if the parallel is Weimar, a few dozen. $100 will become one new dollar and we will start all over again. I read somewhere, several years ago, this in such a scenario many countries don't bother to devalue coins, just paper because it is not worth the time and effort due to the small percentage of circulating money being in coin: one old quarter is worth one new quarter. Many do of course. But if they don't then keeping coins is equivalent to keeping value. I have no idea whether the claim is true but it should be possible to check. I just never had time to do so.
