6. 15 tons of American gold bullion
Ship: S.S. Central America
Value: $150 million
Known to archeological explorers as the "Ship of Gold," the S.S. Central America was packed with so much gold (15 tons, to be exact), that when it was sunk by a hurricane in 1857, it sent the U.S. into economic crisis. Seriously.
Re-discovered in 1988 by the Columbus-America Discovery Group of Ohio, over 30 insurance companies tried to lay claim to sunken treasure.
After failing to pay back his crew and investors, Tommy Thompson, the group’s leader, went into hiding in 2012 and was found in Boca Raton, Florida, in 2015. Since Thompson and his technicians only recovered three of the reported 15 tons of gold in 1998, a judge has given Odyssey Marine Exploration permission to recover the rest of the gold, which will be used to pay off Thompson’s investors and crew.
