This could be just my interpretation but that means that 1 new dinar will be equal to 1000 old dinar which will both be equal to .85.
So that is still technically not a "RV at .85" it is a re-denomination
It means that both 1 new Iraqi dinar currency will be equal to 1,000 old Iraqi dinar currency.
So if you have 25,000 old IQD you will have 21.25 USD
If you have 25 new IQD you will have 21.25 USD
I'm just pointing out what is really being said in the article. I believe in the RV whole heartedly I just don't want people misinterpreting an article
