In North Carolina. All were found on the same site. Does any agency related to documenting such finds care? I tried to report the finds to the state but I received no response. It seems redo you'd that no one tracks this.
Try posting this in /r/askanthropology, you may find people there who actually work in that area and who could help you report them. You can also email someone at a university. UNC Chapel Hill is well known for their archaeology (most likely within the anthropology department). Other universities surely have archaeologists too (again, they will usually be within an anthropology department). If you can find anyone whose research is in North Carolina they may be able to register them for you or be interested for their own research. You can try private consultants too; look up Cultural Resource Management (CRM) firms in your area and phone them.
Can you show us pictures? Can you also please document where you found them in as much detail as possible:
take photos of the area where you found them
take a GPS waypoint or record the latitude and longitude or UTM coordinates (you can do this in Google Earth if you are able to find the location
make detailed notes about where they were, what they were found with, and how they were arranged relative to each other. Don't leave anything out: were they in a farmer's field or a forest? On the ground or did you find them when digging in your garden? What was the weather like? What did the landscape look like? Were there any other artifacts or small broken flakes of stone that looked similar to the points? And so on. Detail and context are key.
Don't post the photos of the site and all the details here, because we don't want anyone who just wants to loot the site to know where it is, but save that information for an archaeologist who helps you. Arrange a site visit with them, if at all possible. And finally, thank you for actually wanting to report this and make it known; so very many people collect projectile points and other artifacts as though they were freely available things open for sport, when that is actually damaging to the archaeological record and means that we permanently lose significant data, like what these things are, how old they are, and where they were found.
