Hey GrouseMan,
I’d say that you’re looking at a very used up Morrow Mountain Variety.
Quartz was a favored lithic all along the Atlantic Coast.
You can see tiny and very uniform resharpening flakes taken all along both blade edges in Pic #1. The basic shape is consistent with that type. However, if Pic#3 is directed at the base (? seems snapped off), it may have been a different stemmed point type.
Just observations. I defer to the experts in your region.
