7. SS Islander's Evasive Gold: In a bit of irony the SS Islander that sank in 1901 was recovered in 2012-without any gold.
Why is it on the list? Well the Mars Company, the expedition, crew thinks the gold may be on the sea bed as a result of moving the ship.
They did find gold dust and pieces of gold on the recovered ship but that's about it.
Mars Company estimates the treasure will be valued at over $250 million therefore they are planning another expedition.
You can see part of the ship on the banks of Admiral Island while the rest is in Seattle.
