Which Edition Are You Reading?
Potter's
Treasure Diver's Guide came out in three versions. The original was published by Doubleday in 1960. A revised edition followed in 1972, and that is the one most people know. Florida Classics Library reprinted the 1972 text as a paperback in 1988, which is the copy you are most likely to find today.
The revision cutoff matters. If you have the 1972 edition, everything in that book reflects what was known — or unknown — about sunken treasure as of more than fifty years ago. If you have the 1960 original, add another twelve years to that gap. A great deal has happened since.
The book still earns its place on the shelf. Potter dug through Spanish colonial records, Lloyd's of London shipping registers, and 19th-century maritime insurance files to build his location catalog, and that archival work holds up. What does not hold up is the technology section, which describes equipment that dive shops today sell as antiques. And a significant number of the wrecks Potter listed as unfound have since been located — some recovered, some protected, some still being argued over in court.
Potter's book also happens to be what put Mel Fisher on the trail of the
Atocha. That alone earns it a permanent spot in the history of the field.
What's Been Answered
The Big Finds Since 1972
The Atocha — Florida Keys
Potter devoted serious space to the Spanish treasure fleets of the Florida Keys, and this is where the most dramatic changes have happened. The
Nuestra Señora de Atocha, a Spanish galleon that went down in a 1622 hurricane off the Florida Keys, was found by Mel Fisher in July 1985 after sixteen years of searching. The motherlode alone gave up gold bars, silver coins, emeralds, and jewelry worth hundreds of millions of dollars. It remains one of the largest confirmed treasure recoveries ever made. Several of the 1715 fleet wrecks that Potter described as only partially worked have since been heavily salvaged as well.
The San José — Colombia
Potter knew about the
San José but had no idea where it was. Neither did anyone else for a long time. The Colombian Navy found it in November 2015 near Cartagena, lying about 2,000 feet down. The Colombian government calls it the most valuable shipwreck in history — estimates put the treasure at around $17 billion, including 11 million gold coins, 200 tons of silver, emeralds, and intact Chinese porcelain that survived 300 years on the ocean floor. As of 2024, robotic submarines have been exploring the site and pulling up new artifacts. Legal battles between Colombia, Spain, and private salvage companies are still running. Nobody has touched the main treasure yet.
The Maravillas — Bahamas
The
Nuestra Señora de las Maravillas went down in 1656 after colliding with another ship from its own fleet and crashing into a Bahamian reef. Potter covered it. What he could not have known was the scale of what came after — nearly 3.5 million artifacts pulled from the site between the 1650s and the 1990s, with more found in recent years by Allen Exploration, including gold and emerald jewelry that had belonged to members of a Spanish military order. The Bahamas Maritime Museum now holds much of the collection.
The SS Central America — Off the Carolinas
This one is not in Potter at all, because it was not a colonial treasure ship. But it belongs in any honest account of modern treasure recovery. The
Central America went down in a hurricane in 1857, 200 miles off the Carolina coast, carrying 21 tons of California gold rush gold. It was found and partially recovered in the late 1980s using deep-sea robots — technology that simply did not exist when Potter was writing. The recovery required inventing new equipment just to reach it.
Books That Fill the Gaps
Every title below was published after Potter's revised edition. Together they cover the technology revolution, the major finds, the legal fights, and the human stories that Potter had no way to include.
Narrative Nonfiction
Ship of Gold in the Deep Blue Sea
Gary Kinder · 1998
The full story of the
Central America recovery. Kinder spent years researching it and the result reads like a thriller. It is one of the best accounts ever written of what modern deep-sea treasure hunting actually looks like — the engineering, the legal battles, the money, and the people who drove the project. If you only add one book to the shelf, this is the one.
Shadow Divers
Robert Kurson · 2004
Two American divers find an unidentified German U-boat sixty miles off New Jersey in 1991 and spend years risking their lives to figure out which submarine it is. No gold, no silver — but no better book exists about the obsession that drives serious wreck divers, or the physical reality of what deep wreck diving demands of a person. Considered essential reading in the wreck diving world.
Pirate Hunters
Robert Kurson · 2015
The same two divers from
Shadow Divers go looking for a 17th-century pirate ship called the
Golden Fleece in waters off the Dominican Republic. They find it in 2008 after a search that kept leading them to the wrong location. Direct follow-up to
Shadow Divers in tone and in the people involved.
The Sea Hunters
Clive Cussler and Craig Dirgo · 1996
Cussler, known for his adventure novels, funded real shipwreck searches for decades through his National Underwater and Marine Agency. This book documents many of those expeditions. Reads more like adventure narrative than technical research, but the fieldwork behind it was genuine and the wrecks he located are real.
Atocha and the Spanish Fleets
Treasure of the Atocha
R. Duncan Mathewson III · 1986
Mathewson was the archaeologist who ran the scientific side of the Atocha recovery while Mel Fisher ran the salvage side. He writes honestly about the friction between those two worlds — the treasure hunters who wanted to pull things up fast and the archaeologists who wanted to document everything in place first. Nobody else had a better seat for this story.
The Atocha Odyssey
Pat Clyne
Clyne was on Fisher's crew and a close friend of the family for years. He fills in the human side of the story — the years before the motherlode, the loss of Fisher's son Dirk in a diving accident, the creditors, the court fights, the long stretches when nothing went right. Includes photographs that were never published elsewhere.
Pieces of Eight
Kip Wagner
Wagner was the first person to crack open the 1715 fleet wrecks along Florida's Treasure Coast, starting in the early 1960s before side-scan sonar existed. He found his first coins walking the beach with a metal detector. The book shows how the work was done at ground level, before the technology arrived that everyone now takes for granted.
Reference and Research
The Shipwreck Hunter
David Mearns · 2017
Mearns is a marine geologist who has located more than 25 major shipwrecks around the world. The book covers his methods, his searches, and the technology that made them possible. Of all the titles listed here, this one comes closest to what Potter was attempting — a broad, serious guide to how the work is done — but written with tools and knowledge Potter never had.
Encyclopedia of Sunken Treasure
Michael Hatcher and Anthony Thorncroft
Hatcher pulled 150,000 pieces of Chinese porcelain and gold from a Dutch East India Company wreck in 1985 — the
Nanking Cargo — in one of the most valuable single salvage operations of the modern era. The encyclopedia he and Thorncroft assembled covers major finds worldwide and functions as a reference volume in the tradition of Potter but updated for the post-technology era.
A Caution
One Category to Read Carefully
David Hatcher Childress wrote a long series of books called
Lost Cities that covers territory similar to parts of Potter — buried treasure, lost mines, hidden caches in jungles and deserts. The books are wide-ranging and genuinely entertaining. Childress has no academic credentials, though, and his claims regularly go well beyond what his sources can support. Worth reading for leads worth following up, not as a reference you'd put serious money behind.
The archival research Potter did — digging through Spanish colonial records, Lloyd's registers, and 19th-century insurance files — has not been matched in a single volume since. That work is still useful as a starting point for any research into Caribbean, Atlantic, or Pacific wrecks from the colonial era.
But Potter could not tell you what ROVs, magnetometers, and side-scan sonar changed about this field. He could not tell you about the legal framework that now governs nearly every wreck site in international waters, or the court cases that have dragged on for decades over who owns what. He could not tell you about the
Atocha, the
San José, the
Central America, or dozens of other finds. The books above fill those gaps. Read them alongside Potter, not instead of him.
