This looked interesting. So I looked up Sterling Currency Group. Yes indeed, their website home page emphasizes that they are selling (and buying) Iraqi currency.

Here is their website:

This is a clip from the banner of their main page:

Their Facebook page (here) has a comment from a guy (10 hrs. ago) giving a link to the story of the raid. He says:

Charles Sussmann Scary the dealer I buy Dinar from is getting raided

Their Facebook page also has a cool picture of the "new Iraqi Dinar"

Sterling Currency Group says this about the new dinar note:

The new Iraqi Dinar is one of the most technologically advanced banknotes in the world today. The Iraqi Dinar contains advanced anti-counterfeit measures which are easily identified and extremely difficult to reproduce. These features include:

1. Watermark
2. Metallic Ink
3. Security Thread... See More

The possible link of Sterling and TntTony is mentioned in a comment to the article about the "dinar scam" (rumor?):

i think its dinar buyers themselves who are responsible for most of the hype and misinformtion being spread, although there are and have been rumors going around for a while that tnt tony acutally works for sterling currency group and though they deny it he seemed tony accidentally on his show the other week slipped up and said he worked for them and then quickly corrected himself, do a google search and you can find some blogs and message boards about it and listen to the tape and decide for yourself

Considering the new more secure dinar note above, is it possible that ONLY these new notes will be convertable at a higher rate?
