Assuming no-one else knows about the safe. Wouldn't you at least mention it in a will or other document? Or if someone knew you had some stash, wouldn't they look for it? I remember a program on TV, where they opened a few hundred old bank boxes hoping to find a treasure map. They of course did not find anything. Wouldn't you check many times if any box had anything of value before decommissioning them? There is something very exiting and addicting with mystery boxes though...
