United States Gold Coins An Analysis of Auction Records Vols I-VI By David W. Akers Hardcover

This Series of 6 books covers United States Gold Coins.  The intent is to provide the reader with a comprehensive listing and analysis of auction records for every U.S. Gold Coin. Mr. Akers explains how, with a mathematical equation, he arrived at the average grade of each coin in the series.  Mr. Akers also includes comments, photographs and information on coins that have sold through rare coin auctions.   I included some pictures, Vol. 1, showing the format which every volume follows.
