In the waters off Florida’s east coast lurked the trove of gold worth a fortune that no one would find for 300 years. It seemed the treasure story concluded in 2015 when one or more divers successfully found 51 gold coins — a triumph that drew news media attention. But now, a state investigation adds a new twist to the saga. It turns out there was a much larger total amount of valuables at the time — actually 101 gold coins, state investigators say.
