Nuestra Señora de Atocha ("Our Lady of Atocha") was the most famous of a fleet of Spanish ships that sank in 1622 off the Florida Keys while carrying copper, silver, gold, tobacco, gems, jewels, jewelry, indigo, and Spanish coins from Spanish ports at Cartagena, Colombia, Porto Bello in New Granada and Havana bound for Spain. The ship was named for the parish of Atocha in Madrid.

American treasure hunter Mel Fisher and a team of sub-contractors, funded by investors and others in a joint venture, searched the sea bed for the Atocha shipwreck for 16 and a half years.

The Atocha shipwreck and its mother lode of silver, gold, and emeralds was finally discovered in the spring of 1985.

Part of the recovered treasure included large silver bars as pictured here:

All of our Atocha coin and nautical products use 100% Atocha silver from bars like this one.
