Daniel Sedwick in his foreword says:

The concept of collecting coins from shipwrecks is relatively new, practically unheard of before the 1960s, when metal detectors and SCUBA diving began to make shipwreck salvage commercially viable. Since that time, coins that were previously considered melt-value items have taken on new lives as historical objects, tangible relics from maritime tragedies related to storms, war, piracy or navigational error (and combinations thereof). What better way to appreciate history than to hold in your own hands actual objects that were there firsthand?

This latest work from Peter Jones describes his collecting journey through several centuries and
nationalities worth of shipwrecks around the world. Peter did not just collect the coins--he collected the histories, and he spent countless hours researching and writing about the journeys that brought each coin to him. In many ways, this book is inspired by and expanded from Tom Sebring's 1986 classic Treasure Tales. Indeed Peter is very much like Tom was--eminently curious about every topic and eager to share every bit of knowledge to be found.

In the process Peter has created this masterful book, a veritable Handbook for Treasure Collectors. Just about every treasure wreck is here, or at least the most important ones, meticulously organized by nationality and time period, with tables of data throughout and quick reference summaries at the end.

While eminently readable, this is not just a handbook or history book--it is also a picture book, supremely illustrated with top-quality coin photographs, maps, portraits and other graphics that bring everything to life. All five W's--who, what, where, when and why--are not just answered but shown. Such a beautiful book is nothing short of inspiring. So whether you are an advanced treasure collector or just curious, enjoy Peter's journey in these pages and experience the rush of truly owning history. The real treasure is knowledge!
