Inherited possible native artifacts, “nutting stones”, pendants?

[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!

Welcome. You'll have to look carefully at the holes. Some sedimentary rocks have them as fossil holes from ancient marine animals.
