Among its significant historic sites is the Reed Gold Mine, a National Historic Landmark. The first gold discovered in the United States was found here in 1799, resulting in a gold rush in the early 1800s. So much gold was mined that President Andrew Jackson established the US Mint to control it. This was an area of cotton cultivation in the antebellum era and industrialization through cotton mills in the late 19th century. Coleman Manufacturing Company, started in 1897, is believed to be the first cotton mill in the nation to be built, owned and operated by African Americans. It was owned by W.C. Coleman, John C. Dancy (collector of customs), and partners primarily from Wilmington, North Carolina, although investors also came from capitalists in the county."
