A Guide Book of United States Type Coins (2nd ed.) by Q. David Bowers. Published 2008 by Whitman Publishing.
Part of Whitman Publishing's "Official Red Book" series, this valuable resource has been completely updated, including coverage of several new type coins issued since the first edition was published. The first chapter is a concise history of U.S. coinage, which alone is enough to make the book a must read. Chapter 2 covers several options for building a high quality type set and is followed by an explanation of the most widely used grading system for U.S. coins and by tips for being a smart buyer. The bulk of the book is a wonderful treatise on U.S. type coins of each denomination, from half cents to $20 gold pieces, and from the first federal coinage into 2008. Information for each type generally includes color photographs; circulation and proof mintages; size, weight and composition; the designer(s); keys to collecting; aspects of striking and appearance; current and historical market values in several grades; and certified coin population reports. A great addition to the library of any coin collector! 282 pages.
