American State Quarters: The DEFINITIVE GUIDEBOOK to COLLECTING STATE QUARTERS, by David L. Ganz, is a must read for any numismatist interested in collecting State quarters casually as a circulated set or as an investment as a set registry set. A driving force in the founding of circulating commemoratives, David Ganz gives a unique view at the history, founding, and legislation of State Quarters. This part of the book is very dense, but gives a lot of interesting background as Ganz served on the CACC. David Ganz then gives an excellent five-page overview of the mintage process and a brief history of coins. He moves to the collecting and investing part of State Quarters, how grading affects the value and mint errors. The next part of the book is on the individual coins, where he spends about three pages per state discussing the state, its design, designers, design history and mintage. The second section of the quarter listings is outdated on the copy I picked up from my local library, as it was copyrighted 2008 (the second edition), but David Ganz goes through the price records, error values, and finally a very useful guide on grading one of the 50 issues. He concludes each listing with an investment potential, what grade it is considered an investment, and the potential of circulation finds. Because it is outdated, some of the price guide is dramatically off, but it can still be used as a general marker on what year's errors are especially valuable. Overall this book is a must-read on 50 State Quarters, and a 4 out of 5 star book.

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.

Hi coin nerds (I hear that WAY too often)!
