Not too many details on this, but Odyssey Marine Exploration has brought an estimated 500,000 coins into the United States from a shipwreck in the Atlantic. The company isn't describing the wreck or its location but there are clues that the treasure may be from a 400 yr old ship sunk some 40 miles off the southwest coast of England. That puts it in international waters, and Odyssey has a court order granting them rights to salvage.
