Hello,everyone! I found a Lincoln Cent from 1970 that weighs 3.42 grams,a 1975D Lincoln Cent that weighs 3.28 grams and 1971D Lincoln Cent that weighs 3.29 grams.Is this an error or something common? Many thanks!  |

Is your scale accurate? That seems odd that you would have three coins overweight

Scale is working fine, it's accurate. I was suprised when I find out the weight. And I found data that Weight Tolerance for copper cents is +/- 0,13 grams and for zinc cents +/-0,1 grams. Is this Weight Tolerance true? |

That tolerance looks correct. Can you upload some photos?

Can we see a full obverse and full reverse image of the 1970 cropped to size. Also a picture of the edge of the coin could be helpful. What is the coin diameter in millimeters? Also, is the obverse to reverse orientation correct (should be coin orientation). Is the coin magnetic?

I check with the magnet,does not stick.Orientation is also OK,but still need to check diameter.I will post photos of both sides and the edge today |

Thanks for the additional photos and information. It appears your coin is overweight due to a rolled thick planchet. Not sure what kind of premium this would carry, maybe someone else will chime in. Nice find. http://www.error-ref.com/rolled-thick-planchets/ |

None that I know of. If you have a clear cent tube, fill it with coins. When you look at the edges of the coins, they are pretty much all looking like your coin. It is common to see them look like that.

All three coins are on rolled thick planchets. But the 71 D and 75 D are just so slightly out of tolerance that they wouldh have no premium value (.04 and .05 grams over respectively) The 1970 is further off, .18 grams heavy, but probably still not enought o command a premium. I normally think a coin needs to be at least .3 to .4 grams beyond the tolerance range before an error collector will start to pay attention to it. So a thick planchet cent would need to be 3.54 to 3.64 or more to gain interest.

Thank you all for informations.I also think that this is not very,very rare or valuable,only if it is much heavier.I was checking more coin weights today-nickels,dimes,quarters,half dollars and dollars,but nothing special was found.
