Set of 3 different colors. Indian vignette engraved by American Bank Note. Set of 3. The Calumet and Hecla Mining Company emerged as a prominent copper-mining enterprise located in Michigan's Copper Country. During the 19th century, it distributed over $72 million in dividends to its shareholders, surpassing any other mining company in the United States at that time. In 1864, Edwin J. Hulbert identified a copper-rich area that would later be recognized as the Calumet Conglomerate, dating back to the Precambrian era.

This discovery occurred in Houghton County, Michigan, situated between the affluent Cliff mine to the northeast and the copper mines of Portage Lake to the southwest, albeit at a considerable distance from both. To secure the land rights, Hulbert established the Hulbert Mining Company in 1864, subsequently founding the Calumet Company in 1865 with the support of Boston investors. The following year, the company created the Hecla Company, distributing shares of the new entity to Calumet shareholders. Hulbert held significant shares in both companies and oversaw mining operations.

However, despite the presence of rich ore, he lacked the practical expertise necessary for extracting, crushing, and concentrating the ore. In light of Hulbert's insufficient progress, the company appointed Alexander Agassiz, the son of the renowned geologist Louis Agassiz, to manage the mine in Michigan.
