This link, http://www.csasi.org/states/nsc/, is to the Piedmont Archaeological Society’s Home Page and is the very best resource I have every found for helping me understand the different cultures from which Native American artifacts in North Carolina receive their identification. Overstreet is also an excellent resource. It is divided into regional sections of the United States and has a very good section devoted to the Eastern Seaboard which includes North Carolina, South Carolina, Virginia and West Virginia. The unique feature of Overstreet is that it gives an at least relative indication of what the value of artifacts found in North Carolina is. (I personally am so attached to my artifacts, having found each one myself, that I tend to think their values underpriced. I know you hunters and collectors will appreciate my perspective.) However, if you are interested in learning the science related to identifying the difference of one artifact from another, please take the time to read through the information on the Piedmont Archaeological Society’s site.
