Nickel (United States coin) - Wikipedia
A nickel is a five-cent coin struck by the United States Mint. Composed of cupronickel (75% copper and 25% nickel), the piece has been issued since 1866. Its diameter is 0.835 inches (21.21 mm) and its thickness is 0.077 inches (1.95 mm). The silver half dime, equal to five cents, was issued from 1792 to 1873 before today's cupronickel version.
Nickel - Simple English Wikipedia, the free encyclopedia
Nickel is made from its sulfide by heating it in air. This oxidizes the sulfide to sulfur dioxide, leaving liquid nickel behind. This nickel is not yet pure and not ready for use. Pure nickel with a nickel content greater than 99% is made in an electrolytic process. In this process, the nickel is dissolved in bath of sulfuric acid.
