Don’t worry shipwreck hunters…according to some estimates, as much as $60 billion in sunken treasure still lies beneath the ocean’s surface.

How much Treasure still lies Underwater?

No one knows for sure how much treasure lies underwater, waiting to be discovered. But according to recent estimates, as much as $60 billion in sunken treasure still awaits the intrepid treasure hunter. Here’s more on underwater treasure estimates from Popular Mechanics:

It’s been a busy month for shipwreck headlines and shipwreck hunters. The team that announced the discovery of the Port Nicholson, a World War II–era British merchant ship found 50 miles off the coast of Maine, says it bore 71 tons of platinum ingots worth about $3 billion. Other shipwreck hunters turned up the HMS Victory, which sank in the English Channel in 1744 with a “secret” cargo of gold valued at $1 billion. And, in an episode that shows the high stakes of shipwreck salvaging, Spain is currently recovering the estimated $500 million haul of gold and silver from the Spanish galleon Nuestra Señora de las Mercedes that sank in 1804; an American company found the ship but lost court cases to Spain over the rights to the treasure.

All this undersea treasure hunting got us wondering: Just how much money is out there buried at sea? We put the question to marine archeologists, a historian, and a shipwreck hunter. Their answers ranged from “Who knows?” to “$60 billion”—and each was instructive…
