Sorry for the ancient bump.
I have a golden age book that is missing a corner of an interior page. Maybe 2 inches by 1.5 inches.
One one side it affects a text story, the other side is a cartoon where a bit of art is affected but you can still read the gag.
None of the main stories are affected at all.
The comic is a F+, F/VF.
If I sold it, would I be right in selling it as 6.5 or 7.0, and qualify it with the piece missing and deduct some $$?
("6.5 with an interior page corner missing (w/measurement) that affects a text story").
