don't know what they would be worth, but its a nice set, i wouldn't sell, i think the copper culture is totally intriguing, and wish more was known about them, personally i believe they were dealing with cultures from over seas. generally known to span fron 2000 to 7000 years ago. i think the Menominee Indians are there decedents, because of the early missionary reports of their lighter skins and features differing from other bands they encountered and possible interaction of other cultures. just a piece of my mind and could be way off base
