Query: Good book but maybe not what you expect.

I enjoy reading Mr.Salyes' books and this one is no exception. He easily one of the best current numismatic authors. This work does a great job of covering the types of counterfeits along with their history and an overview of how they are created. It is a very good book for anyone beginning to collect ancient coins. One thing the book is not is a catalog of counterfeits nor a guide on how to detect counterfeits. These subjects are beyond the scope of any general work and are dealt with by various numismatic associations and their publications. So if you are only looking for a manual or catalog move on.
