1979 penny from unopened mint set weighs 2.98 grams

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

Thanks..

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

 

It still within the tolerance +/- .13gr.

 

Ok thanks

 

Mine only weighs 2 grams. Is that significant? Thank you

 

@Raymond Lee : Please start a new thread with pictures and a description of the coin. 2.5g is the nominal weight for the copper-plated zinc cents from mid-1982 on.

FWIW, some boards want you to use older threads if it's the same basic topic. Here we lean towards separate threads and frown on hijacking.

Hi Raymond Lee, The difficulty is helping is that your Scale or Balance , you are only giving a single number which would be grams, but the weight of the cent as developed by the U.S. Government uses 2 decimals places after the period. Eventually you can get a X.XX weight similar to something like 3.10 or 2.66, etc.
Amazon and other sources are fairly reliable.

i have a question wahat is legal as far as cleaning coins to pgns is it. so used a few cleaners most seem to do more dmage what acually works.

 

o and answer to x.xx is 3.10 perfect is 3.11

 

does ezest work tried ms 70 with luck on a curtain variety also pink spray a vegan worked a bit if you don't touch coin scratch very easily. also tried some flitz work but if left in looses shine works in close to a few seconds but if not clean enough whenm you spray it on wou,t clean coin properly and to do it to many tim,e can run into problems

 

When dealing with older coins in any case new no harm until left in to long. so what works right keeps sheen and doesn,t fade and also good with the numerologist.
