The research began with the 2015 discovery of what is believed to be a Clovis point arrowhead, which Gramly says could be 12,800 or more years old and worth as much as $15,000.
At top, a real Clovis Point is on the left. It is 3 inches in length. It is made from Bailey Chert and was found by Dan Figgins on the Malden Plain, Dunklin County, Missouri. The point on the right, was made by a knapper in 1999 who lives in Connecticut. It has been artificially aged in an attempt to deceive.
