Buffalo nickel
Iron Tail (Oglala Lakota: "Sinté Mazá" in Standard Lakota Orthography) (1842-May 29, 1916) was one of the most famous Native American celebrities of the late 19th and early 20th centuries and a popular subject for professional photographers who circulated his image across the continents. Iron Tail is notable in American history for his distinctive profile on the Buffalo nickel or Indian Head nickel of 1913 to 1938.
