In the lincoln album this is designated as " Stamp usa three cents no grill ". It is also not hinged. I have photographed it with back light in a couple of photos and you can see the stamp colors etc coming through in reverse. Also you can use a jewelry loupe to examine the stamp and there is no grill as it says in my album and have no reason to doubt it.
