1876 So-Called Dollar HK-47, Independence Hall Dollar

Coin Details

Description

This commemorative so-called dollar (HK-47) from 1876 celebrates 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. William Barber designed the official U.S. Mint medals for the 1876 Centennial Exposition, establishing the standard for American exposition medal artistry. 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

Strikings of HK-47 are scarce. Post-Civil War era medals were often distributed at events, with many entering circulation as pocket pieces rather than being preserved as collectibles.
