So this is what I’m thinking on the types
Tan left Abbey snap base lol
Black beautiful Yadkin
Dark brown with stripes Bolen
Last one Savannah River with some red
Probably coastal plains chert but not sure on the black one.
These are from a old collection from the 60s
Let me know if I’ve typed them correctly none show being ground but you know how water and sand can remove and add it.
