A much larger scan at 600 or better might help someone here determine the grill. I'm far from an authority on this issue. If I'm remembering correctly

the color and NY cancel could indicate a #85--but that's probably a very long shot. I'm not in the camp of "don't lift it". I've lifted stamps from covers to identify--particularly W/Fs. I've even had the APS authorize lifting before sending stamps in for expertizing. I don't recommend lifting where its problematic about whether or not the stamp originates.
