I found this 1985 D penny while cleaning out my work truck this evening. It has a subscript “o” struck after the 5 in 1985. I have never seen anything like it. Attached is both a scan and a separate photo of the penny. It certainly has seen some love through circulation over the years…there is high degree of wear on this penny and pitting about Lincoln’s right lapel. Nonetheless, the subscript "o" struck following the date intrigues me. If anyone can shed some light on what we’re looking at here I would be grateful. Thank you in advance. FireTide Seattle, WA
I think I know what that is. It's an extremely valuable type of error called a PMD. Very few coins have it and this is a very rare type of PMD. I think it's worth a few thousand and you should send it to PCGS. Just kidding, it's worth $0.01, it's damaged.
Surely, you jest? I don't particularly care about the condition of the coin; it's beat to heck, it's been in circulation and probably at the bottom of a few fountains who knows... What I do know is there is a subscript "o" struck on it. I've never seen a penny with this before. Maybe there are 1 or none like it. It was difficult to take a photo up close of, but I used my iPhone 6 and that's as good as she gets. It is clearly a struck "o" with raised edges, symmetrical, etc. Not plating or rotting. Perhaps I can procure a magnifying glass and take a photo of the image magnified. It isn't surprising those replies heretofore cannot identify it and thus chalk it up to a plating, rot or damage. Like I said, I've never before seen a coin with this subscript struck letter "o." FireTide Seattle, WA
It's a broken plating bubble with zinc rot underneath. It just happens to look like a 'subscript "o"'. Nothing special.
And about Storage Wars, there was an episode with an 1872 trade dollar. Want to know how I immediately found out it was fake?
Rick, noncents, idhair, I really appreciate the wealth of experience you carry and taking the time to reply. I'm guessing that may well be what it is. Is it not possible a grain of debris was present as the time the coin was struck, thus appearing as an "o" where said debris was pressed? If you might kindly take a gander at these additional, magnified photos I'm attaching and let me know if I can confidently walk away from this penny. Thanks again, truly I appreciate your time.

Well that would have to be an indent into the die to form that - not something that fell into the die - that would cause an indentation in the coin!
burst plating blister is what it is, worth 1 cent spend it or save it so you know for the next one you find...
