Found this the other day where I find some pottery, etc, was told it was a counter weight for an Atlatl , made from soap stone, hope someone can help with identification and value

Good question
Maybe more pics will help like the bottom and any holes it might have. Maybe something for size

That's a pretty unusual design, similar to a keeled boatstone. Keep in mind, all these ancient artifacts uses are speculation, as there's no one one from the time frame to verify it for you.
