While this is all well and good, it boils down to two things: I can either buy a raw book or I can buy slabbed book.
All things considered, I still prefer to purchase the slabbed book. At least I have some semblance of an opinion other than my own and the person selling it to me.
The question then becomes:
Are CGC books worth their premium over raw books? Will uncertainty regarding micro-trimming cause the slabbed premuim to erode?
To me they are still worth more than raw books. It depends on the individual and how they view the situation. Personally, I don't think so as CGC's opinion is still worth more to me than someone I don't "know."
A lot of the time CGC's opinion is worth more because of the people I do know.
