#20: The Nuestra Señora de Atocha Treasure Still Holds Secrets
The Spanish galleon Nuestra Señora de Atocha sank in 1622 near the Florida Keys while carrying gold, silver, jewels, and other valuable cargo from the Americas. Treasure hunter Mel Fisher found the famous wreck in 1985 after years of searching. Important sections remain undiscovered, so the estimated $450 million treasure continues growing.
