The term was once widely used for all sorts of things, including nautical bollards and consumer products including soap, chewing tobacco, stove polish, canned oysters and shrimp, golf tees, and toy cap pistols among others. It was often used for geographic features such as hills and rocks and geological objects such as geodes. The term appears in several US patents for mechanical devices prior to about 1950. 
In the U.S., more than a hundred "Niggerheads", and other place names now considered racially offensive, were changed in 1962 by the U.S. Board on Geographic Names, but many local names remained unchanged. In 1955, the Aughinbaugh Canning Company of Mississippi renamed its "Nigger Head Brand" oysters to "Negro Head Brand" following pressure from the National Association for the Advancement of Colored People.
