John1 Moderator United States 56855 Posts	Posted 11/26/2010 07:06 am Found a '83 LMC and it weighs in at 2.2g. Is this within mint tolerance or is it collectible? Any value? Thanks for your input, John1 Report this Post to the Staff

KenKat Pillar of the Community United States 4085 Posts	Posted 11/26/2010 10:23 am 2.2g seems awfully low to me. I weigh my 1982's all the time to be sure and they typically range maybe 2.48 to 2.53 if they are of the zinc variety. My 7070 US Type Set My 7100 Lincoln Cent Set (now with updates!)

clairhardesty Pillar of the Community United States 1027 Posts	Posted 11/26/2010 10:33 am 2.2 grams may well be some sort of foreign planchet. It is slso about the right weight for a dime (2.27g nominal). I have never heard of a dime being plated and struck as a cent but I suppose it could happen. How about some pictures of the coin?

clairhardesty Pillar of the Community United States 1027 Posts	Posted 11/28/2010 09:19 am It looks like a normal cent. Even the rim looks normal which means that the blank was probably the right diameter (not a dime). It may just be a thin planchet. The weight of 2.2 grams should be well out of tolerance but I really don't know what the specs were in 1983 (it would be nice if the mint would publish a definitive list of coin specifications and tolerances every year). If it is just a thin planchet, the question is how common was that in 1983? Report this Post to the Staff
mikediamond Pillar of the Community United States 2737 Posts	Posted 11/28/2010 10:16 am 2.2 grams is below tolerance for a copper-plated zinc cent. Your cent was undoubtedly struck on a planchet punched out of rolled-thin stock. Among zinc cents, these can get as light as 1.6 grams. Among copper-ally cents, the weight can be as low as 1.4 grams.
