Two are grey Hornstone, the lighter colored (2&1/16") looks more like a chalcedony than a flint, higher silicate, so it really took some fine pressure chipping (serration) along the blade. The points are from along the Pond River, Hopkins of Muhlenberg County, Kentucky--the last twenty+ years in my collection. Starting (next) with the hornstone Graham Cave--1&3/4" with a tip that had a secondary use that left it really, really dull. Even a guess as to what use dulled the tip that extensively would likely be off-the-mark, so I'll leave that to the next owner to decide. The final point, another 2&1/16" piece shows very little basal edge grinding---but a cornernotching that suggests Early Archaic Kirk Culture--a VERY well made piece. All three are real, waiting for a new home. Shipping is $9.00, checks or M.O.s are the two ways to purchase them as I do not use paypal-type services--Roy A.
