There almost was: The Lybian Gold Dinar.
But 'luckily' the bankers prevented this from happening
i was just to say this.
Gaddafi was about to create a gold backed currency http://www.goldstockbull.com/articles/libya-invasion-gaddafi-plan-gold-dinar/
Saddam Hussein was planing on a similar thing (the initial part was he made only euros tradeable for iraq oil)
JFK signed executive order 11110 5 months before he was assassinated which basically should/would have abolished the FED
"lucky" for us they are terrorists and victims of assassinations before they could destroy the USD
Along similar lines, the Taliban outlawed poppy plants and burned down most of the fields right before 9/11 (95% of of pharmaceutical opiates come from Afghanistan, this would have bankrupted pharma companies)
i also want to add something about libya... Gaddafi just gave 10s of thousands of rpgs and over 2 million assault rifles to the "genocide victims" fight the rebels... yea right, like that's something a murderous dictator would do, especially when you consider only ~1 million out of the 6 million in Libya are against Gaddafi, Hmmmm
