Book excerpt: More than 550 coins photographed and discussed in this book are NOT KOSHER...in other words they are forgeries, often intended to deceive unwitting collectors. David Hendin has collected and researched these neglected forgeries for more than 35 years, and now makes his diagnostic methodology and huge database of photographs available to scholars, collectors, and dealers. Hendin writes: "When apparently legitimate college professors and scholars were prepared to authenticate, as genuine, ancient Jewish coins that even a beginning collector could identify as suprious, the time had come to document all those known fakes."
