Warren Harding Magnificent Signed Stock Certificate

An extremely attractive stock certificate signed by future 29th U.S. President Warren G. Harding (1865-1923), then in his role as President of the Tri-Metallic Mining, Smelting and Refining Company of Nogales, Arizona Territory, as "WG Harding" at lower right. Dated October 12, 1905. Countersigned by company secretary N.K. Staley at lower left. The certificate, No. 437, granted 200 $10 shares to one W.H. Kyle. Docketed verso. Expected paper folds, one with a slight closed tear found along the right edge. The left edge is perforated and may have corresponded to a voucher of some kind, hitherto removed. Else near fine. 13.5" x 14."

The certificate itself is a work of art besides the fact that it was signed by a future American president. At top, a print depicting a factory nestled between mountains in northwestern Mexico measures 10.5" x 6" alone. A banner proclaiming "Gold, Silver, Copper" with metallic accents in each respective color, also appears near the top. The geometric border, seal at bottom center, and company seal at lower left are burnished in gold, silver, and copper accents respectively.

The Tri-Metallic Mining, Smelting and Refining Company was first incorporated on June 10, 1903. Though headquartered in Nogales, Arizona Territory, its operations were centered near Nogales, Sonora, Mexico, three miles or so south of the modern day U.S. / Mexico border. The original company prospectus was broad and ambitious in scope; its founders hoped to capitalize on any or all of the following business ventures: gold, silver, and copper mining; oil, gas, petroleum, mineral, and water extraction; real estate; infrastructure development including the railroad, telephone, and telegraph; and the possible production and sale of electricity. Despite their best-laid plans, not only was the Tri-Metallic never lucrative, it was possibly never even developed, thanks to early-twentieth-century political unrest in Northern Mexico.

It's unknown how Warren G. Harding, then serving as Lieutenant Governor of Ohio, became aware of the Tri-Metallic investment opportunity, or became one of the company officers. Perhaps M.K. Gantz of Troy, Ohio, one of the company co-founders, recruited a fellow Buckeye?
