You are correct to say that it probably wont happen. But don't say "no way". It has happened in the past. Read the link from the The University of North Carolina. It will explain lops perfectly.
Here's a quote from the article.
"Another means of manipulation is currency reform, in which the government introduces a new currency, but makes it difficult for citizens to convert their holdings of old currency. Ignacio Mas (1995) suggests that, while the use of currency redenomination as a mechanism of confiscation is more the exception than the rule, it has been used as such throughout history. For instance, when governments require citizens to exchange old currency for new during a very short period (e.g. one day in Laos in 1976, or three days in Nicaragua in 1988 and in the Soviet Union in 1991), it is very likely that not all old currency will be exchanged. The old currency that is rendered worthless is essentially revenue; indirect seignorage -- for the government"
We've all heard and read that it is illegal to remove dinar from Iraq according to Iraqi law.
I can see it now, Iraq issues a new currency... then tells it's citizens that the currency exchange must take place in an abbreviated time. Give them two weeks... tell them that it has to happen fast because they have to trap all the illegal dinar that has left the country and is in the hands of terrorist and infidel speculators... trap that currency outside of the country. They do not like speculators... Remember Saddam... currency speculation was punishable by death while he was in charge.
