This volume on proof gold has nearly 2,000 illustrations. Every proof gold variety has either a full color photograph or a close-up illustration of pertinent features.
For a work of this magnitude, this is only possible because of digital photography and software.
“John Dannreuther is one of the great numismatic research experts of all-time. His proof coin book is his magnum opus! There is so much detailed information on proof gold coins in JD’s book that I believe no numismatic library is complete without it. And I can assure you this book will be a major resource in the PCGS grading room for many years to come.”
— David Hall, PCGS Cofounder
“There are books and there are more books. Often, to find all there is to know about a specific subject, it is necessary to consult several books, perhaps even a dozen or more. As the author of quite a few books on American numismatics I know this well. No such field work is needed for anyone owning a copy of the present triumph by John Dannreuther, United States Proof Coins Volume IV: Gold. It is a one-volume encyclopedia that includes more historical information than could be found by spending a week or even a month in the National Archives or another of the great institutional libraries! That John was able to create this while at the same time maintaining his prominent position in the world of professional numismatics is amazing.”
