1915 So-Called Dollar HK-405, Panama-Pacific Expo

Coin Details

Description

This commemorative so-called dollar (HK-405) from 1915 celebrates Panama-Pacific Expo. The Tower of Jewels, the exposition's centerpiece at 435 feet tall, was covered with over 100,000 cut glass 'Novagems' that shimmered in the sun and were illuminated by colored searchlights at night. Struck in bronze, this piece combines durability with an attractive warm tone that deepens with age into a rich chocolate-brown patina. Bronze was the preferred composition for many commemorative medals due to its excellent detail retention. Official exposition medals were struck by the U.S. Mint, and the landmark Panama-Pacific commemorative coin set (including the famous $50 gold pieces) made this the most numismatically significant American exposition. 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.

Rarity Notes

Strikings of HK-405 are scarce. Early 20th century medals were often distributed at events, with many entering circulation as pocket pieces rather than being preserved as collectibles.
