1939-1940 So-Called Dollar HK-487b, Charbneau Dollar Incuse "40"

Coin Details

Description

HK-487b is a 1939 so-called dollar commemorating Charbneau Incuse "40". The Century of Progress featured the Sky Ride, transporting visitors 218 feet above the lagoon in enclosed cars suspended between two 628-foot steel towers, and pioneered windowless buildings using prefabricated Masonite and plywood. 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. Later exposition medals were produced by a mix of U.S. Mint issues and private manufacturers, with many struck in lower quantities than the great 19th-century fairs. The Century of Progress and New York World's Fair generated the most varieties. The Hibler-Kappen catalog has been updated and expanded since its 1963 first edition, with later researchers adding newly discovered varieties and extending coverage into the modern era. This piece is a variant of HK-487, distinguished by differences in composition, die state, or striking characteristics that merit a separate catalog entry in the Hibler-Kappen reference.

Rarity Notes

So-called dollars from the interwar period were produced in limited quantities for distribution at events or through numismatic channels. Examples of HK-487b are scarce, with surviving pieces ranging from well-worn pocket pieces to carefully preserved specimens.
