Looks like it could be. Is this a find, or a purchase? If you found it then the location could have historic significance. Did it come from the ancestral range of the Caddo people? Regardless, you should have it verified by a qualified expert in American Indian artifacts.
If it's real and modern, not really worth much. If it can be dated as being real and old, then it could be worth a lot. You're going to have to find an expert though.
