Lincoln Pics- Error?

MrSpud

Hi,
I went through a roll of pennies from the bank today and noticed 2 coins from the 80's with a wierd raised crescent line running parallel to the rim near the date area, almost like they have part of a second rim trying to form or something. Attached are pictures. Is this some kind of error? Thanks, in advance, for any responses.

Appears to be more from machine doubling, rather than error.
I could be off way though, since I'm not a Lincoln fanatic.

This is a form of die fatigue that, for some reason, is largely restricted to Lincoln cents of the zinc era. It's rather common, and much more severe examples can be found without too much effort

Severe die fatigue is generally considered to be an error, if it results in gross distortion of the design and/or field. At a minimum, the failure to replace a die after it's exceeded its useful life is an example of human error.

Thanks. So it is die fatigue. Hmmm... interesting.
