I coated it with white glue/waterIf that plate were mine I would conserve it before it turns to dust. I use a water base polyurethane on pewter buttons. I'm not sure if that is the best thing to do. Maybe someone here really knows conservation of pewter. As far as value, that's probably going to be tough. I've never seen one!!
