I would have liked to see the interior surfaces of the indentations as well. How can I know if those indentations have not been pecked and ground in if I can't even see them?? Sure it's likely natural, but I've been collecting for 60 years and I have found many rudimentary waterworn notched weights because I picked up a "possibility" and was able to detect pecking in or around the notches even though waterworn. Of course this is not a notched weight nor a squirrel effigy. But I would have picked it up to more closely examine the notches, which, again, do not show their interior surfaces in these photos. And I don't think I would need to take up stamp collecting just because I wanted to satisfy my curiosity....
