In 2005, professional numismatist Jeff Garrett and PCGS President Ron Guth co-authored a second edition of the award-winning book 100 Greatest U.S. Coins. The authors surveyed members of the Professional Numismatists Guild (PNG) asking the question, “Which are the greatest U.S. coins?” The interesting results of the survey are presented in order in this registry set, with the “King of American Coins,” the 1804 dollar, being listed as the #1 greatest U.S. coin. Each of the coins listed will have one or more of the following characteristics: rarity, value, quality, popularity, beauty and history. These are the coins of which dreams are made.
