1876 So-Called Dollar HK-35a, Independence Hall Dollar

Coin Details

Description

HK-35a is a 1876 so-called dollar commemorating Independence Hall. Machinery Hall covered 13 acres and housed the 1,400-horsepower Corliss steam engine, standing 70 feet tall and weighing 650 tons, which powered all exhibits through five miles of overhead belts and shafts. The bronze composition of this piece reflects the medallic tradition dating to classical antiquity. Bronze so-called dollars typically survive in better condition than white metal examples due to the alloy's greater hardness and durability. The U.S. Mint struck official Centennial medals designed by William Barber, while private firms produced hundreds of additional varieties. The Centennial group is the largest in the HK catalog. 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. This piece is a variant of HK-35, distinguished by differences in composition, die state, or striking characteristics that merit a separate catalog entry in the Hibler-Kappen reference.

Rarity Notes

HK-35a is scarce in the numismatic market. Production quantities for post-Civil War era commemorative medals were typically modest, and survival rates vary significantly based on the original distribution method and the material's durability.
