Description
Designated HK-331a in the Hibler-Kappen catalog, this 1905 piece commemorates Lewis & Clark Expo. The 1904 Louisiana Purchase Exposition in St. Louis occupied 1,272 acres in Forest Park — twice the size of the Columbian Exposition — making it the largest world's fair in history, with 1,500 buildings and exhibits from 62 nations. Bronze examples of so-called dollars offer collectors an excellent balance of affordability, condition, and aesthetic appeal. The alloy's hardness produces sharp strikes with fine detail that survives handling better than softer metals. Official exposition medals were struck alongside the landmark Jefferson and McKinley gold dollars. Private manufacturers produced additional commemorative pieces sold to the 19.7 million fairgoers. George Morgan, famous for his Liberty Head silver dollar design, also contributed to exposition medal production during his long tenure at the U.S. Mint. The HK numbering system established by Hibler and Kappen in 1963 brought order to hundreds of previously uncataloged American commemorative medals, many of which had been ignored by mainstream numismatic references. This piece is a variant of HK-331, distinguished by differences in composition, die state, or striking characteristics that merit a separate catalog entry in the Hibler-Kappen reference.
Rarity Notes
HK-331a is scarce in the numismatic market. Production quantities for early 20th century commemorative medals were typically modest, and survival rates vary significantly based on the original distribution method and the material's durability.
