Zinc-core pennies have been made since 1982, and are lighter than all-copper pennies made prior to this (2.5 grams vs 3.1 grams). In addition, pennies of the same "generation" can exhibit greater amounts of dirt on them (increasing weight - gross but true), and different amounts of wear to the metal (decreasing weight).
