The 1913 Liberty Head nickel is an American five-cent piece which was produced in extremely limited quantities unauthorized by the United States Mint, making it one of the best-known and most coveted rarities in American numismatics. In 1972, one specimen of the five cent coin became the first coin to sell for over US$100,000; in 1996, another specimen became the first to sell for over US$1 million. A specimen was sold for US$3 million in a 2004 private sale, then resold for US$3.7 million at a public auction in 2010.

The Liberty Head nickel, sometimes referred to as the V nickel because of its reverse design, is an American five-cent piece. It was struck for circulation from 1883 until 1912, with at least five pieces being surreptitiously struck dated 1913. The obverse features a left-facing image of the goddess of Liberty.
