Up for auction is a Utah Copper Company 120g Vintage Poured Copper Ingot

Rare one!  I've only seen one other in 10 years.

Utah Copper Company (UCC) was formed on June 4, 1903 to mine and process low grade copper ore found in a mountain in Bingham Canyon, about 25 miles southwest of Salt Lake City. Steam shovels began working on the mountain in 1906. For the next 100 years, shovels, trains and trucks converted that mountain into the world famous Bingham Canyon Mine, a huge open pit copper mine that is more than three-quarters of a mile deep and more than 2 3/4 miles wide across the top and still growing. In 1915, Kennecott Mines became Kennecott Copper Corporation, which purchased a 25 percent interest in the Utah Copper Company and acquired all assets and property in 1936 forming Kennecott Utah Copper (KUC) . In 1947, Utah Copper Company was dissolved and became the Utah Copper Division of Kennecott Copper Corporation. (from OldCopper dot org and an old listing)
