The enigma of the 80,000 pieces of Eight wreck

[Colombiapictures]

In 1981, when I was in the Bahamas with Bob Marx, we searched for a ship "Rosa", 1817. In the edition of Marx's book Shipwrecks in the Western Hemisphere that we had on board, the ship was supposed to carry 80,000 pieces of Eight on board.
The problem was that the position of the shipwreck mentioned in the book, was impossible. When I asked Marx about it, he said that he left out a lot of information in the book, about the shipwrecks that he hoped to locate and work himself.
We found a shipwreck that fit approximately the date and was in the corrected position mentioned in the book. Later I will describe the site and the 11 cannon.
Digging with an airlift, we found scattered silver coins almost immediately.
In 1985 I returned to the place and found more coins. (The UN scandal)
Recently I decided to write down my treasure hunting stories. I got the book Shipwrecks in the Western Hemisphere, to start off again with the initial information, but it turns out that the edition I got has not the same paragraph as the one we had in 1981.
Does anybody have a different edition?
There is also another mystery connected with that wreck site: While digging with the airlift, I found a heavily encrusted crowbar stuck in the timbers of the ship. It looked like a wrecker had left the crowbar behind many years earlier.
Now I have found information about a treasure hunter that salvaged a considerable amount of treasure from a shipwreck at that approximate location.
