Grease would not take any weight of off the coin. I think what you have is a thin planchet

JimmyD / Errers and Varietys, I did a little searching and you both are correct, "Thin Planchet". Thank you!

AI search results: What Happens When a Thin Planchet Is Used?
The coin may strike with weak or incomplete details, especially around the rims.
It often weighs less than the standard for that coin type.
May also look slightly smaller in diameter if the metal didn't expand fully during the strike.

Very cool find, gigi! I may need to go back and look through my extreme greasers, do not think I have ever weighed them. They may not all be greasers.


CoinForMe, you may want to be careful of what the AI puts out there, it's still learning....

Not searching for politics... just kidding. Yes, you're right, thanks for the heads up.

If I'm honest, I don't even know why I weighed this coin, the only coins I weigh are 1982-D small date, 1983s, 1989s, and 1990s, but that day I just put the coin on the scale without a second thought, under other circumstances I would have just put it aside like a Struck Through Grease without weighing it. From now on I will weight any coin that seems to be greasy, it could be rolling thin or tapered planchet

Gotta agree, appears to be a thin planchet issue.

Close to within US Mint Tolerance:

"The tolerance for the weight of a U.S. one-cent coin is ± 0.1 grams. This means that a new Lincoln Cent, which has a standard weight of 2.5 grams, can weigh between 2.4 and 2.6 grams"
