There should be an overhaul of the grading system and possibly add a new term GNA - Genuine Never Altered to truly describe a real stamp in it's true original state free from alterations to make it appear better than it is.
Well, experts have to be able to
see the repairs in order to certify that. That won't always be the case.
Years ago, when the Honolulu Advertiser Hawaiian Missionaries went up for auction, they
all had some degree of repair. Indeed, some of the repairs were major: tears were sealed, missing pieces were added back in, thins were filled, paper was added at the margins so all four were clear, etc. Of course, this was all done on the up-and-up: the repairs were fully disclosed in the auction catalog, documented in detail.
The best of the repairs cost thousands of dollars to perform. They were done by professional paper conservationists (the kind that work with historic documents in museums). To fill a missing corner, for example, paper fibres were extensively woven into the stamp,
one by one. The fibres were taken from period paper (the main source IIRC was a piece of selvedge from pane margins, so an exact match for the issue). The repair was so good you couldn't tell, even through a microscope, which paper fibres in that corner were original and which fibres were added during the repair. If you weren't aware, you'd think it was a sound stamp.
Now,
that quality of repair can only be done at great expense, so it will only happen to rarities. Of course, that's also where the most value for performing a repair is. Any Missionary with a corner missing would still sell for a healthy amount -- it's a rare stamp and almost all copies have some faults -- but the repaired stamp certainly looks much better and no doubt the auction realization was higher for the repair.
