1862 Indian Head Cent The lowest denomination in use during the Civil War, the cent, saw an increase in its mintage in 1862. The total output of coins for circulation at the Philadelphia Mint, the only facility that struck minor coins at the time almost tripled to 28,075,000 coins. Most of these, especially those struck after August, where hoarded and would not enter circulation until after the Civil War, when federal coins came into circulation again.
