If you take the photo, look at it at a sharp angle to a light like a desk lamp and see 'silvering' the photo is old. Usually appearing in dark areas, silvering is like a silver patina that gets light and dark as you change the angle of the photo to the light. Silvering is an aging process, and only appears on old photos. Silvering would show that the photo is antique.
