Description
HK-304 is a 1904 so-called dollar commemorating Louisiana Purchase. The 1905 Lewis and Clark Centennial Exposition in Portland, Oregon celebrated the famous 1804-1806 expedition with 400 acres of exhibits along the Willamette River, drawing 1.6 million visitors. This bronze so-called dollar represents the standard commemorative medal composition of its era. Bronze pieces were often the primary production run, with silver reserved for presentation copies and white metal for budget editions. 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 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.
Rarity Notes
Bronze strikings of HK-304 are common to moderately scarce. Early 20th century medals were often distributed at events, with many entering circulation as pocket pieces rather than being preserved as collectibles.
