Iraqi tank ends up on Ebay, and a collector bought it. He found 3.2 million dollars of gold in it's fuel tank that was stolen from Kuwait by Iraqi's under Hussein's forces in the 1990 invasion (Gulf War 1)

A tank collector in the United Kingdom and his mechanic opened his newly purchased tank's diesel fuel tanks. Inside were gold bars totaling approximately $2.4 million dollars. Mead found the tank, an ex-Iraqi Army Type 69, on sale on eBay.

The collector and his mechanic had already found machine gun ammunition in the armored vehicle and wanted video proof in case more ammunition was found. They pulled out five gold bars weighing about twelve pounds worth an estimated $2.4 million.

Six months after the end of the war, Iraqi authorities returned 3,216 gold bars under UN supervision. Others they either didn't know about, or missed

The exact history of this tank is unknown but it was built in the early 1980s and has just 1507 miles on the clock.
