It was one of the greatest treasure finds in history: almost 30 years ago, treasure hunters discovered $400 million worth of gold and silver off the coast of Florida from a sunken Spanish Galleon, the Atocha.
But, according to records, even more riches lay on the bottom of the sea, waiting to be found. The Atocha was just one of many vessels that sunk around the area, carrying all sorts of precious metals from the Americas to Spain.
Correspondent John Zarrella caught up with some of the same treasure hunters who found The Atocha. After all this time, the team is still obsessed with finding more treasures off the Florida coast, and he joins them on their journey for riches.
