Rare Discoidal

[Froze2]

I've been told this is an extremely rare piece. The Discoidal is fully grooved, about 3 inches wide and 1-1/2 inches thick. It is beautiful, in great condition, and found near Quincy, Il. Looking to get an approximate value.

Very nice piece..If you don't get a answer here, give the North American Native Artifacts forum a shot. Welcome to Tnet
