The Havana Theory
Season Four introduced us to Gary Drayton, a metal detection expert. Drayton scouted Lot 24, one of the lots previously owned by Samuel Ball, a man who used to be a slave but then became a cabbage farmer and then mysteriously turned into one of the richest men in the area. So, what did Drayton find?

The metal detection expert found British coins from the 18th century, a button, a metal tag with a name, and a lead ingot. The team then concluded that the items might suggest that there used to be a British encampment on the island and that the British naval officers wanted all the treasure to be buried on Oak Island.
