Possession is 9/10ths of the law. I don't know what I'd do. I'm pretty sure I wouldn't immediately turn them over to anyone. I'd probably talk to a lawyer. Taking them to Pawn Stars might actually be a good idea. I'm not saying sell them by any means. But you're liable to get free info and appraisal. From there I would probably sell them at auction, but I really couldn't say.
