National Geographic: Treasure! (1976)

Hurricane winds struck the Florida Keys in 1622, sinking the treasure-laden Spanish galleon Neustra Senora de Atocha. Three-and-a-half centuries later, a former diveshop owner brings her millions of dollars in treasures to the surface, piece by precious piece.
The story of Mel Fisher's quest for the Atocha and her lucrative cargo - estimated at $100 million - is the subject of Treasure!
"Once you see the ocean bottom carpted with gold chains, you'll never forget it," Fisher says of the experience. Fisher's team searched for years without a find. Then, in May of 1973, divers glimpsed their first real treasure. Thousands of silver coins were uncovered in a spot aptly named the Bank of Spain. After the discovery of the coins, Fisher and his crew continuied to unearth the treasure, including gold coins, a rosary, a gold disc, and finally, some silver bars whose registry numbers provied that Mel Fisher had indeed discovered the remnants of the Atocha.
