Found this specimen in a jar of 1983 P one cent coins I set aside for later analysis and this one has some interesting anomalies on the reverse especially. The obverse right rim from 1:00 to 5:00 is heavily abraided. Thanks for any information you all can provide. The reverse contains the most interesting features.
It would be helpful in the other if you posted a photo of the whole obverse/front of the coin. It appears yours has a mix of being struck through grease (very common and adds no extra value) and post mint damage. It’s certainly fun to look at, but not considered very interesting or collectible for error collectors.
The weakness that is on the States area of your coin is a common feature on LMC's. It is caused by the metal trying to fill the larger opening of the Obverse die,Lincoln's lapel. It does take time for the Metal to Flow into all of the dies designs. And the rate at which coins can be Struck does not allow for this. As for the lines seen in that same area, I would say that they are linear plating bubbles. And a plating bubble near the FG at lower right corner of Memorial, Which could be a die chip but it look to round for that. On LWC the weak spot shows up opposite Lincoln Head more often.
Alot can be learned from that coin, it has many things going on. It does make a good multi-error reference coin.
Here is the obverse photo that I originally intended to include in the image array of my initial post. One day I will master the art of coin photography. Its disappointing that there are so many countless features on coins that just do not appear on the images of a coin, but that are easily visible to the naked eye.
