1952 "Flying D" Lincoln Wheat Cent

This is a fun one to find, but because I had never found one in decent shape I never really understood why it was considered an RPMl (looked like just a die chip to me), until I found this UNC one. It has split serifs (2) that I had never been able to see on the circulated examples I had found previously AND the die chip that gives it its name. It is listed in CC as a 1MM-031. I am still learning something new every day.
