My mom was cub scout den mother when I was a cub scout and we lived in Kewanee, Illinois and she became acquainted with a fella at the post office, who I still recall had a house full of artifacts and she ask if she could bring us scout's over and he could show his collect to us and talk about how his massive collection came to be. and give us pointers on how we could find are own artifacts to start a collection. His started with his granddad and I still remember him saying his granddad had a cotton bag tied to his waist and as he walked behind the plow he'd be picking up arrowhead after arrowhead filling that bag up as he plowed the fields in the old days. I can only guess that's how this item was spotted walking behind a plow and then something shiny rolls over to the surface. Bet that hand who got the 3 hogs thought he got the better end of the deal back in those days.
