I'm looking at the mintmark, the "In", the r in trust, designer initials, the C in Cent and a couple other oddities. There's not any variety of this coin minus just RPM. So I'm guessing PMD or die wear. Thanks. Edited- also the R in America.
I guess so. Looks good for 39 years in circulation though. Think of all the things hitting it and wearing it down over the years.
