How Much does One Penny Weigh?

Sounds like a trivia question to me! The weight of a penny depends on their dates. Indian head pennies, struck between 1864 and 1909, weigh 3.11 grams. Lincoln pennies, minted between 1959 and 1982 also weigh 3.11 grams. Lincoln head pennies produced from 1982 to present weigh 2.5 grams.
