So in your scenerio, if I was a rich Iraqi and I tucked away 25,000 dinar, worth approx. $75,000 US dollars at that time, in a sock when the war started for safe keeping. It is now worth very little in Iraq and approximately worth $21.00 US dollars now. Under your plan it have to be traded in for a new $25 dinar bill and then at some time later the value of the dinar would be increased up to say a value worth $3.50 US dollars. That would then make your original stash of $25,000 dinar, worth $75,000 US at that time, now 25 dinar worth $87.50 US dollars. I'd be pissed at the Iraqi Gov. if I were him!
