1958 So-Called Dollar HK-513, Butterfield Overland

Coin Details

Description

Designated HK-513 in the Hibler-Kappen catalog, this 1958 piece commemorates Butterfield Overland. San Francisco's 1939 Golden Gate International Exposition occupied Treasure Island, a 400-acre artificial island built from 300,000 tons of boulders and dredged sand, later converted to Naval Station Treasure Island. 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. 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, 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

HK-513 is scarce in the numismatic market. Production quantities for post-war era commemorative medals were typically modest, and survival rates vary significantly based on the original distribution method and the material's durability.
