The point came to me from a Union county, Illinois, auction a couple years back, but any history was lost with the passing of the last owner. The flint (or chalcedony) is a partially translucent material I've yet to identify, but even using the state-by-state "Lithics identifier" site (Illinois Lithic Material) I've not figured what the flint might be--closest I've come is called "Strawberry Chert", but without a whole lot more info this 3&7/16" Dixon/ Gary may be a piece left as 'unidentified' , a designation I've seen used on various authenticators' COAs. That's not a 'cop out", no one can know every chert found. Width is 1&7/16" by 7/16" max thickness (or the piece would have been more translucent). The making of the stem ran into a 'grain' almost a stack in the flint, so the stem isn't as perfect as the blade. The only damage is to the end of one barb--a flat spot. There is still soil under the hinges of the flint, patina--guaranteed authentic in all regards. Shipping is$5.00 with checks or M.O>s welcomed. Sorry, I do not use paypal--Roy A.
