Therefore, later 1936 pennies and nickels featured the mirror-like "brilliant" finish used on the other coins of the set. ![]() Proof cents and nickels produced in early 1936 had a satin finish, which was unpopular with collectors as it closely resembled the standard circulation strike finish. Like previous proof coinage, the new coins could be bought individually, but unlike previous coins, they were also offered as a set.

In 1942 the Mint was mandated to conserve tin and as it researched several materials, developed a one-cent coin of only copper and zinc which alloy proved entirely satisfactory to the life, quality, and appearance of the coin. The bronze one-cent piece was first legislated during the Civil War by the Act of April 22, 1864, which set the one-cent piece at 95% copper and 5% tin and zinc.
