1 Cent 'Lincoln Cent' Presidency - Bronze

The 2009 Lincoln cent is a one-year anomaly in modern U.S. coinage — four distinct reverse designs issued simultaneously to mark the bicentennial of Lincoln's birth, the only time the cent has carried multiple reverses in a single calendar year. Congress mandated the return to the original bronze alloy that year, abandoning the copper-plated zinc composition introduced in 1982. The four reverses, designed by different sculptors, depict episodes from Lincoln's life and were produced at both Philadelphia and Denver.

Collector demand was intense enough that the San Francisco Mint struck satin-finish specimen sets as well.
