I used to walk miles and miles of Iowa ground and creeks searching for Artifacts. I had about a gallon of heads. Gave some to friends and family, still have the better ones, spear points mostly. Have a few axe heads as well. Always on the search walking to stands during Bowhunting. Arrowheads are worth what people will pay. But think about this. One day early in my searches i was out hunting with an older fellow. I found a nice arrowhead and he came over bent down as i picked it up. He closed my hand with his and said, " In your hand is a ancient piece of the past, made by an ancient man 5000 or more years ago. You,are the first white person to hold it in your hand since he lost it. Think about that. Every piece i have found since that day has affected me. One day while Hunting i found a head. It is beveled like a Grizzly head of today. I had it aged and was told by a state arch, that it is over 9000 years old.
