I get removing some, again as you stated it has happened in the past.
One example I just really do not get is the
Siamese Pages.
As Matt said it doesn't come up often, but that is the draw to them. They are production error that does not happen that often and definitely should be on the label.
Especially since they can not be seen from the outside!
This would be like removing Double / Multiple Cover or Mark Jeweler's / National Diamond Insert . These are things that definitely have an impact on the value/ desirability.
I have a couple of books that have siamese pages/wraps that I had planned on sending as QC gets fixed, but if they will not note these then that doesn't even make sense.
This doesn't even bring up several of the completely valid concerns others have over potential misuse of lack of information.
This change needs to be better thought out before whatever they decide to roll out. Hopefully they will tweak this to alleviate concerns and erosion in trust of CGC.
