The 4-cent Silver Centennial commemorative postage stamp was issued through the Virginia City, Nevada, post office on June 8, 1959. The stamp's design, based on an old print, depicts Henry Comstock at the Mount Davidson site of the rich silver deposit discovered by Patrick McLaughlin and Peter O'Riley.
The central subject is framed by "Silver Centennial 1859 1959" at the left and top and "United States Postage 4c" across the bottom in a lettering style suggested by P.T. Barnum type, a series based on lettering fashions of the 1850s.
Designed by Robert L. Miller and W.K. Schrage, the stamp was printed by the rotary process, electric-eye perforated, and issued in panes of fifty stamps each. An initial printing of 120 million stamps was authorized.
