Inherited possible native artifacts? Drills?

[Misnomer]

Hi everyone, thanks in advance your help with these. My grandpa left pails of rocks in his garage when he passed, which after some investigation over the years I’m thinking might be native artifacts? Doing some spring cleaning so I decided to finally clean them up and snap some pictures to recruit some help. I’ve tried to group them wth similar stones. Time to either dump these in the garden or find out if there are indeed some legitimate artifacts in there to display!


The rocks in the first two pictures appear to have notches ina circular pattern around the rocks? Next two pictures I grouped together because they all seem to have points like a drill maybe?

I don't think there are any artifacts in this group. Drill points would still have relatively sharp points.

I suspect you’re right, to the garden they go. Do you know why the rocks in the top pictures have those jetted notches around the rock? It’s as if someone was trying to split the rocks by punching little holes around them? Thanks for your help.
