The exact name of that rim anomaly slips me at the moment. I don't "think" it a planchet error. Not a 100% sure. I've seen many of these rim type issues plus the gas bubbles I see on your coin. Here's a link that may narrow it down for you: http://www.error-ref.com/part-v-planchet-errors/
Thanks, I think I found it. A partial collar strike, slightly off center? Sure a lot to learn on these Lincoln cents...
This is no collar error, nothing more then a worn die . Shield cent are famous for this . Here's one form of a collar error, it's called a stiff collar strike .
I can't see a partial collar error at all. What I do see is a strike by a ever so slightly misaligned and very worn die. It's nothing special.
