The template was then coated with a thin layer of metal by electroless nickel plating, and the template is etched away, leaving a free-standing, periodic porous metallic structure. Nickel was used as the microlattice metal in the original report.
Jefferson nickels have been minted since 1938 at the Philadelphia and Denver mints and from the San Francisco mint until 1970. Key dates for the series include the 1939-D, and 1950-D nickels. The 1939-D nickel with a mintage of 3,514,000 coins is the second lowest behind the 1950-D nickel.
