    I have a 1979 penny that weighs 2.98 grams . The 1979D in the set weighs 3.11.

    Do I have a rare coin. My research says it could be brass. Thin planchets are usually attributed at 2.4 or under. Any thoughts or tests I can try to determine?

    I weighed 5 other UNC pennies and they all weigh 3.10 to 3.11 so I know the scale is accurate and my woman has another coin scale and it weighed 2.98 on hers as well

    No. Standard is that 95% are 3.11 +/- 0.13g
