You’ll have to be at least an Open Water certified diver. The wreck site isn’t deep.

Mel has been pulling up gold, silver, emeralds and other artifacts from the Atocha for years. They’ve even found another lost Spanish treasure ship that they will (or have already) started salvage operations on.
You get to keep what you find up to a value of $2500. The cost of the trip. Check the website out to see what they’ve brought up already.
