Early editions attribute authorship to the publisher Chester L. Krause, and Clifford Mishler, although starting with the second edition Colin R. Bruce II was the actual chief compiler and is given an editor or senior editor title on later editions. According to "Coin World", Bruce was the lead cataloger and editor of every annual edition from 1976 through 2007, retiring in 2008. George S. Cuhaj is the current editor, with Thomas Michael credited as market analyst, although Krause collate contributions from many collecting experts and dealers.
