VERY interesting!! May I use your photos for educational purposes?? I am thinking that this is a folded over rim fin, although it has some rim cud characteristics. I am guessing that it would be attributed as a Rim Cud at this site: http://cuds-on-coins.com/lincoln-cent-cuds-1982/ Reasons I lean towards a rim fin the way the thick rim fin trails off at both ends it occupies approximately 90⁰ of the circumference and I have never seen a die with that degree of circumference broken off Here is a study I recently did of the question:
@Pete Apple ... I downloaded your PDF... thank you for the great information. Also, you asked..."May I use your photos for educational purposes?? "... yes.
Misaligned Die Strike will cause a High pressure strike which will cause a Finned Rim. Your Cent is Misaligned, So as Pete stated.. it is a folded over finned rim IMHO
Let's not forget that beautiful finger print on the reverse. Sends shivers down my spine whenever I see those.
Thank you Mike Diamond! This means I will need to change my research report and definitely add this as a rather rare example!
I've seen longer ones, some equal to or surpassing 180 arc degrees (my memory is too hazy to be more precise). All of them were on cents, for some reason.
