There are a couple of German souvenir sheets that are gummed on the back of the stamps only, but ungummed on the margins (B33 and B58). I noticed that the never hinged catalog value is MUCH higher than the hinged value (as is the case for much of Germany). Now what's to stop someone from carefully washing the hinge marks off of the sheet without damaging the paper? I am viewing a B58 on
ebay that is supposedly MNH, but the scan of the back looks like the paper is a little disturbed where someone might have removed hinge marks. If there were hinge marks, I suppose someone could have been even more careful in cleaning off the evidence without damaging the paper at all. Or am I confused, and the sheet counts as MNH as long as the stamps themselves are MNH? (This seems to be probably not the case, because nobody would hinge the stamps, which are in the center of the sheet.)
