I can't vouch for this site, but it seems interesting:
In 1991, the Kuwaiti dinar's value fell precipitously from over
USD$3 to near worthlessness. It rapidly shot back after liberation.
Anyone who acquired Kuwaiti dinars at the low point, was soon
able to cash in for many hundreds of times the purchase price. It all
happened so fast, most of the world never even had a chance at getting any.
After years of trade sanctions, and rampant counterfeiting, the Iraqi Dinar has plummeted from its pre-Gulf War value of over USD$3, to mere fractions of one US cent. What was once the equivalent of more than $82,500, can now be purchased for around $50.
http://www.betoniraq.com/index.html The thing that bothers me is that it looks like they mail you the paper currency. I would prefer to open an account with a fixed market, Not recommending it, but it's an interesting idea. It's very high-risk but potentially high reward.
