I don't remember seeing that one, but I have two boxes of unlisted variety coins so maybe something similar in there. Agree it is likely an earlier die stage would be necessary for listing. When I look at the west side of the upper curve of the 6 I see a lot of pointy bits sticking out to the northwest, making the pointy bit to the northwest on the mm a bit suspect. It certainly looks like an RPM, but likely there is enough compounding stuff going on to make it difficult to really figure out what's what.
