The Spanish galleon "Nuestra Señora de Atocha" sinks off the coast of Florida during a hurricane with a significant cargo of treasure. Of the 265 people on board, only five survived. The wreck was lost for over three centuries.
On July 20, 1985 treasure hunter Mel Fisher's Treasure Salvors company discovered after a 16-year search. The cargo included a fortune in silver and gold, copper, indigo, tobacco, and 20 bronze cannons, among other items. The recovered treasure was valued at approximately $400 million.
