I used to love doing that kind of stuff. I have/had an uncle by marriage who was head of the Anthropology/Archeology Dept. at what was then West Texas State at Canyon TX. In addition to being the head curator at the really fine museum at the university, he used to go on a lot of digs and I was lucky enough to accompany him on a few of those. Great fun.
Ringel05 is our Civil War expert in the Coffee Shop. Don't know that he is a relic hunter but he joins in the re-enactments here and there and makes his own very authentic costumes.
