Ernest Richards, PLUS VLTRA Newsletter: Enrada Publications, October 2007:

"This popular book has been out of print since 1995 and unavailable for a number of years now, so this [fourth] edition should be a most welcome addition to the market! Greatly expanded from theprevious edition (more than 100 pages longer!), this 20th Anniversary Edition contains a long new section on the shipwrecks that have yielded cobs over the years, complete with a foldout map andspecified bibliographies for each wreck. Also, the assayer section incorporates the latest research information, with specimen photos of most of the assayers (not separated into a photo section asbefore). The values in the back, of course, have been updated. What has not changed, however, is the appeal to both beginners and advanced collectors alike, as well as dealers and jewelers who workwith cobs. The Practical Book of Cobs offers readers a look at the following topics: Historical background / Elements of design / Market values / Extensive bibliography / Complete ID of mint marks,assayers, and period / How cobs were made and used / Treasure Fleets and other shipwrecks that produced cobs / How to buy and sell, and how to spot counterfeits."
