This is an 11 inch plate. I can't identify the Oneida mark. Is it sterling? The shield has 2 lions on the side and a O or C L on the shield. It also has the initials DPH. Any information would be appreciated. http://www.wowway.com/~johnmor/500dpi.jpg http://www.wowway.com/~johnmor/initials.jpg http:...
