Newman Portal Adds Bill Bugert Doubled Date Census

Bill Bugert is well-known as the authority on Liberty Seated half dollar (1839-1891) varieties and has published well over a thousand die marriages in his ongoing series, A Register of Liberty Seated Half Dollar Varieties, with six volumes published to date. In addition, Bugert maintains separate censes on the more notable issues in this series, including the rare 1878-S. Bill has developed an extensive network of contacts with the Liberty Seated half dollar community, and any public appearance of an example will not go unnoticed. Bill’s pedigrees are lengthy, and the bar to offer a new coin as “fresh to the market” is exceptionally high. Bill’s latest publication, A Register of 1849 WB-6 Dramatically Doubled Date Liberty Seated Half Dollars, represents a census of the 38 known examples of the WB-6 variety and includes photographs of nearly every piece.
