Grinding Stone?

Found this along a river in southern Ohio. Any ideas?

Post it in the.Native American artifact forum. I think it could be a weight from a drill

Dig until your arm falls off

Definitely not a grinding stone. Could be a weight, could be a target for arrow practice, could have been a "toy" or part of a game. I agree you need advice from someone specialized in native american artifacts for your area.

Need more pics of all edges and a better pic of hole from both sides

Maybe a weight, but I'm thinking it may be a discoidal

The best known type of so-called discoidal stones is circular and has concave depressions on each lateral surface which vary in degree and depth, and sometimes a hole occurs in the center. These are most often explained as game pieces for an ancient Native American game called "Chungke."

Few more pics



There are dimples on both sides 180 degrees from each other. You can see one in the pic between my thumb and the center hole.

I think you have it right in your title. Grinding stone from a bench grinder. Material looks like aluminum oxide.
