Error Other | 1984 Lincoln Cent with Weight 2.7 grams

[Chamfre008]

Could it be possible that a 1984 Lincoln Cent can weight 2.7 grams. I just encountered this coin and have my doubts as to the coin weighting this amount. The normal weight should be 2.5 grams. Any comments or research on this topic would be beneficial. Thanks. For the purpose of this discussion I have repeatedly weight this coin and the weight is exact in point.

My thoughts are most likely just rolled thick planchet stock, or possibly extra thick plating. At that weight, I wouldn't think it was the wrong material, but a specific gravity test would be needed by an expert, I believe. I am not sure what the official mint tolerance is on this. Anyone know?

Does the coin seem thicker than usual? If so it could be this.

There is an outside possibility that it could have been struck on a foreign planchet as well.

Thick planchets on zinc cents are more unusual than copper cents, but certainly not unheard of. I have a 1983-P struck on a 2.8g. planchet. And no, I don't think it's anything other than thick rolled planchet stock.

Why are you still here? You always ask for help on a coin, then try to sell false errors and varieties on eBay.

Hmmm, that's right, I knew the name sounded familiar, I'd almost forgotten.

Passing off non-error coins as something other than what you've been told they are is a no-no around here.
