Hi pizzaman,
I answered a similar question to this not long ago, so I am going to put down more or less the same response.
If a lop occurs, your dinar may not be worthless, however you may have difficulties cashing it in for dollars, for example. Dealers may charge a premium to exchange. These are uncertain times. There will be a new currency issued at some time. This has been alluded to in numerous articles.
A 'lop' and dinar rise maybe a possible scenario. However, a new currency would be issued and again exchanging the current dinar may be difficult depending on where you are in world. For example, I live in the UK and there is not a problem exchanging at a bank here at the moment. However, in the US for example, banks do not exchange dinar any longer, as far as I am aware. Please bear this in mind.
If a new currency is issued, you may have difficulties exchanging it through a dealer for the NEW, 'new iraqi dinar' currency. Despite the assurances that 'dinar dealers' are bandying around the internet. I believe Iraq will keep a much tighter reign on a new currency, if issued, and I don't suppose the 'central bank daily auctions' will continue in there present form.
I hope that helps and welcome to the forum. :smiley:
