My father hunted and collected Indian artifacts. These are a couple item in the collection I am not totally sure about. The first item ? The second item I believe is a scraper. Not totally sold on the third item even being an artifact but could be.

The first item looks like a pecking/shaping stone(hammer stone) 4 making points and other flint tools,I have one almost identical to it,mine has some caliche deposits on it though.

I think that first one is a gorget preform, 2nd geofact, 3rd flake, and last a broke knife.

Other than the first one which may have had some flaking along one edge they all look like natural rocks to me and not artifacts.

That 2nd piece almost looks like it has a worked bit. Hard to tell from the picture. Does the leading edge on the 2nd piece have very small (visible to the eye, with a magnifying glass) parallel lines etched into it? It could just be a rock but I haven't given up on it quite yet.
