I found this coin roll hunting, and is bright and lustrous but looks worn down. I am also not ruling out struck thru grease, since the hair details in the head are mostly gone, and there is clear flatness in some areas on the reverse. I have compared this to a 2015-P nickel for comparison.
If this is PMD, then it don't look like it since the luster is still intact .
I was leaving my 2 biggest possibilities out there, either Grease Filled Die or extreme die wear consistent with VLDS dies. After looking at it more, it is definitely not a PMD event; it has cartwheel luster both sides. I felt this one could go either way, but not necessarily both at once which is not likely.
