1904 So-Called Dollar HK-311a, 4 Mo Good-Luck Dollar
Strike TypeCoin Details
Description
Designated HK-311a in the Hibler-Kappen catalog, this 1904 piece commemorates 4 Mo Good-Luck. The Louisiana Purchase Exposition produced the famous Jefferson and McKinley gold commemorative dollars — the first U.S. commemorative gold coins — alongside numerous so-called dollar varieties in silver and base metals. Struck in bronze, this piece showcases the detailed die work typical of American commemorative medals. Bronze's natural patina gives aged examples an appealing warm-brown surface that collectors prize. 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. Morgan's artistic legacy extends beyond coinage to include numerous commemorative medals that showcase his distinctive portrait and eagle designs. The Hibler-Kappen catalog, first published in 1963 by Harold E. Hibler and Charles V. Kappen, systematically organized American so-called dollars for the first time, assigning HK numbers that remain the standard reference today. This piece is a variant of HK-311, distinguished by differences in composition, die state, or striking characteristics that merit a separate catalog entry in the Hibler-Kappen reference.
Rarity Notes
Strikings of HK-311a are scarce. Early 20th century medals were often distributed at events, with many entering circulation as pocket pieces rather than being preserved as collectibles.
