numismatic coin value

Like every American coin weigh? (1900-present)?

I found the composition of coins throughout American history, But does anyone know your weight? I have many parts that have no numismatic value because planes are used, but the weight could help me identify a melt value.

cents dollar from 1909 to 1982, except 1943 chrome steel 3.11 grams, 2.70 grams of steel, 1943, 1982-2009 2.5 grams. Two weights used in 1982. It will take longer than I have now, so I write and I'll do the rest. I allows e-mail.
