"The ocean floor is dotted with an estimated 3 million shipwrecks."
More than a few of them are believed to be loaded with gold, silver, platinum and other precious metals, collectively with values too high to make any reasonable estimations. One of the richest discoveries in history may have occurred in January 2009, when a salvage company found what many believe to be the Port Nicholson, a British merchant navy ship sunk off the coast of Newfoundland by the Nazis in World War II, alleged to contain as much as $4 billion in gold, diamonds and platinum.
