ctrcrazy2 Valued Member United States 210 Posts	Posted 09/26/2019 6:59 pm Found a LMC with a weight of 2.5 grams, thought that the weight did not change until 1982 and was wondering if anyone has found or knows of any LMCs with that weight. Thanks in advance for any information Report this Post to the Staff

Spence Moderator United States 34428 Posts	Posted 09/26/2019 7:27 pm That does seem to be underweight (below tolerance). Can you please confirm that the 2.5 g weight is correct by checking your scale with other copper cents?

coop Bedrock of the Community United States 62064 Posts	Posted 09/26/2019 7:32 pm The strike looks normal. If it were under weight it should be showing a weaker strike. Here is an example of a thinned planchet error: Note the weakness of the strike? If yours is that far under weight, then it would be showing a weakness on the coin. Or the weight is wrong?

ctrcrazy2 Valued Member United States 210 Posts	Posted 09/26/2019 7:46 pm I have checked the scale with a 1979 and 1981 LMC and both those weighed 3.09 grams on the scale Report this Post to the Staff
Spence Moderator United States 34428 Posts	Posted 09/26/2019 7:53 pm Ok thanks for confirming. As @coop points out, we sometimes see thin planchets, but then the strike is much weaker, either overall or to one side. Please measure the thickness and diameter. If you are using calipers, just be careful not to scratch the surface.

ctrcrazy2 Valued Member United States 210 Posts	Posted 09/26/2019 7:57 pm Checked the thickness sandwiched between a 1979 and 1981 and it does appear thinner with weak strikes on both the obverse and reverse. Thanks for the replies Report this Post to the Staff

Really helpful to see a full reverse and obverse if you get them. Words of encouragement are one of the major food groups. We need to consume them regularly to thrive and grow.
