Profitable Coin Collecting, by David L. Ganz, is an interesting book that explores market trends and investment in lucrative performing coins. A respected and polished numismatic author and driving force behind our circulating commemorative coinage, David L. Ganz has masterfully written a book on coins as investments. I believe that this book should have special appeal to deep pocket collectors (see my review on One Coin is Never Enough). The author investigates the Salomon Brothers survey on coins as an investment. David Ganz goes on to investigate its shortcomings and how it revolutionized the coin industry, as its effects still affect our collecting 44 years later. While the whole book is filled with charts, this section is particularly dense with eye-opening charts and illustrations. He moves onto what creates value in a coin and how grading has affected today's market. He finishes the first half of the book with investment strategies, especially focusing on pre-20th century proof coins.
