It does look like a common design, but, as mentioned by others, there are many important factors. If it is made of quartz (which it does seem to be at a glance) then its makers probably considered it to be a "worker" point (my own term, not widely recognisable). I call it that because quartz is hard as hell to work by hand. The only real advantage to it is the fact that once you get the shape you want, it is really hard to chip or shatter it. The quartz point is like the carbide tip of the ancient world. So, it wouldn't have been made for display. It was made for use. The size makes sense for an arrow (not a dart, nor a spear), which would have been used for war or repeated hunting.
I don't think that cazisme's post was stupid. On federal land, disturbing or collecting that artifact is illegal. In the state of Georgia (where I live), it's effectively illegal to collect an archaeological artifact on any public land. Around here, you can only keep it if it's found on private land and you have written permission from the land owner which allows you to possess it. Some states are very strict about the fact that the state owns and controls everything, as is the federal government.
