Zyrus Press 71-2-4 9780974237121 - Numismatic Forgery, by Ruddy, James, Paperback 19th ed.

This book takes the reader into the hidden workshop of the criminal forger, and explains the methods and techniques that every serious coin collector should know before they purchase a rare or expensive coin. The informational interviews Larson conducted with the infamous master forger, Mark Hofmann, at Utah State Prison in the late 1980s lay the foundation for a number of methods revealed in this book. Hofmann is widely known for his forgery of historical Mormon documents, but Hofmann's coin forgeries continue to serve as a note of caution and a source of frustration and embarassment to many collectors and dealers. Larson's book offers a detailed and brilliant approach to how rare coins are privately manufactured, and promises to forever change how collectors and dealers of rare coins understand and approach counterfeit detection.
