There are two simple yet effective naked eye techniques that a collector can use. The first is to closely examine the suface by holding the card at nearing 180 degree angles to a good light so you can observe the gloss and surface texture. Added ink and other stuff will often show up . The second is to hold the card up to a bright light and see how the light shines through. Built up corners and such will often be revealed this way, as the built up areas will be brighter or darker than the rest of the card.
