Its "pagan", and personally, I think that lady at Penn State has been taking too much liberty at night at the frat house parties. Any relic that has withstood the elements that well has got to be worth something.
Just because they have a file full of unexplained items doesn't mean it isn't worth anything, it means that that research department finds sucking on beer bongs more important than doing their job.
Ah, I know I ticked off some Penn State people with that little rant, but I feel that way about every college, so deal with it.
I would approach some indepent historians instead of college "scholars". Anyway, good luck with it.
