If you or someone you know has fallen victim to an Iraqi dinar (or Vietnamese dong, Indonesian rupiah, or any other foreign currency) “revaluation” investment scam, the FBI has set up a website to report the seller of these worthless currencies.
Currency revaluation schemes have been around for a long time, and have never once paid off for anyone except the people charging a commission for the sale. Iraqi dinar scams have been going strong since 2003, and the currency has yet to do anything except lose value.
There’s an article at Forbes.com that goes into further detail on this type of scam.
