American collectors are undoubtedly familiar with the popular U.S. state quarters program and the new Presidential Dollar Coin. Such limited-edition coinage is part of a long tradition, dating back as far as the Columbian Exposition of 1893. "Encyclopedia of the Commemorative Coins of the United States" celebrates America's rich numismatic history with the most thorough and wide-ranging volume ever compiled on U.S. commemorative coinage. Written by the country's leading expert on numismatics, the Encyclopedia provides indispensable information for a broad spectrum of readers - from the reference librarian and the student to the serious collector. Anthony Swiatek not only provides a history for each coin, but also a detailed analysis of contemporary collecting facts, including quantity in existence and the coin's current value. Swiatek further discusses counterfeit and doctored coins; mint errors; and even other related collectable materials such as cancelled coinage dies. With pages of illustrations of coins as well as rare photographs of historical memorabilia, packaging, and other ephemera, the Encyclopedia is a must-have for the discerning investor and the casual hobbyist.
