1. Tons of American gold coins
Ship: RMS Republic
Value: As much as $5 billion
The RMS Republic was a luxury ocean liner that first set sail in 1903 and was known as the "Millionaire's Ship” because of its immensely wealthy passengers. However, after being sunk in a collision with the S.S. Florida in 1909 while en route to ports in the Mediterranean, several rumors have surfaced regarding the ship’s cargo.
Captain Martin Bayerle, who re-discovered the sunken cruise ship in 1981 roughly 270 feet below the surface and approximately 50 miles south of Nantucket Island, says the ship was hauling more than just people.
In his book, The Tsar’s Treasure, Bayerle alleges that the RMS Republic went down with $3 million in gold coins that was headed to Russia on loan from the U.S. government.
Two recovery missions have come up empty handed, but Bayerle is confident that the coins, which are valued from hundreds of millions to even billions of dollars, are down there somewhere.
