I found this cent several years ago and thought it looked really unusual! I put it in a flip and filed it away! Just found it again and decided to post it here to get some feedback/opinions!!! First thing I noticed was the last number is missing from the date! I assume this means it is a greaser! Then I noticed the mark/gouge on Lincolns back! Can't imagine how that could happen at the mint so I assume that is post mint damage! The weird part came when I looked at the reverse! A lot of the letters are completely or partially missing as well as the middle of the monument! This is also the case on the obverse but not as prevalent! Then I noticed the coin is much thinner that a normal cent, and wondered if that prevented a full complete design when the reverse was struck! Looking forward to your thoughts!!!!
Looks like it could be a thin planchet error. Not enough material to fill in details/devices. Lets see what others are thinking. What has me wondering is the wear on the obverse. Almost acid like. But the rest looks legit to me.
I also say struck on Split Planchet. It was struck after the blank planchet split. The details on the reverse is how it usually appears when this issue occurs.
My first thought when zi saw your original photos was the coin was struck on a planchet that was only half there. There was not enough metal to fill in the coin and that’s why it’s missing so many details. I didn’t read all the post but then @paddyman98 showed a split planchet coin from his collection. I believe he is correct as to what this is. A great error that should be graded by a TPG.
