1989 1 Oz NWTM Homestake Mining Round PF

Homestake Mining Company operated from 1876 through 2001 and was one of the largest gold mining companies in the United States. They produced poured bars in the late 1970s. Beginning in 1981, they produced yearly silver rounds that celebrate milestones in the company's life. The mint producing the rounds from 1981 to around 1984 is unknown. Beginning in 1985, all of the rounds have a uniform reverse and were minted by NWTM, which itself began operations in 1984. Some of the later rounds exist with gold relief. The mintage is unknown, but the rounds are scarce.
