An arrowhead is an artifact because it was from a long time ago.
The use of an artifact as a primary source is different than the use of a written primary source because when you exacavate for an artifact, you may have to make guesses. However, with a written primary source, you don't need to guess as the writing inside will have the answers to your questions or guesses.

One option is to contact your local university's archaeology department. Another would be to contact one of the many commercial artifact authenticators out there. I use these guys and have been very happy with their professional service. http://www.jacksongalleries.com
