I came across this one a while back and put it a side. Finally got around to taking pictures. This is a 2002 P with the Crown Jewels floating above the crown. Grease filled die error. This is a first time I’ve seen this happen on the crown.
She is missing the top of her head. Not a grease filled die. It would be from a heavy polishing, or lapping of the die. This removes the lower relief details. In this case the top of the head.
