(1904) So-Called Dollar HK-320a, LA Purchase Expo Machinery & Metallurgy Brass
Strike TypeCoin Details
Description
Brass with a reeded edge, HK-320a pairs two industrial halls of the Louisiana Purchase Exposition. On one side is the hall for mines and metallurgy, which the lettering sizes at 525 feet by 750 and costs at 500,000 dollars; on the other the much longer Palace of Machinery, 525 by 1000 feet, at 497,000 dollars. Hibler and Kappen list the aluminum striking first, as HK-320. The 1904 fair marked a century since the United States bought Louisiana from France, and St. Louis won the honor partly because it had served as territorial capital in 1804. Its exhibition palaces spread out in a fan from a central festival hall. Brass, 36 mm.
