HEy Mamadough...by the way, your first name wouldn't happen to be Kelly...would it??
If so, I finally remember the name of the point I was trying to tell you. It's called a Yadkin, and some archaeologists believe it is the first true "arrow"head used in the Southeast, although that is up for debate because nobody really knows for sure when the bow and arrow was invented here in America. I have seen examples of Yadkin points from other people's collections that are very close in size to the one you found. Yadkin points are between 2,500 and 500 years old.
Hamilton arrowheads, also called "Mississippian Triangles", came later, and date to between 1,500 and 500 years ago. They tend to be smaller, thinner, and are usually made from higher quality flint or quartz.
