what is a gold crown 1 worth

Question to RKC: In one of fastone's brunstone pictures there appear to be semi-circular grinding marks. Am I seeing that correctly? If so, is the presence or lack of grinding marks a reliable indicator?

Those are hand swipe marks, and you won't be mistaken when you see the half moon grinding marks when they span the width of that slate from side to side.

This is some picts of the slate. It looks grey from the bottom with no tooling marks. It also has a radius on the pocket shelves like a water fall. Is this what is called Pennsylvania bluestone?

Yep, sure is.

RKC is this a quality product? I am just concerned about not having slate.

I# it's not broken, it's perfectly fine.

It may be Pennsylvania Bluestone, but it almost certainly is sandstone.
