DJIsn't this operation really about protecting the big $$$$ cards, the 8's, 9', and 10's for those who have a lot invested into cards?
It isn't so much (IMO) about the T206 PSA4 common as much as it is about perhaps them (big $$ collector) having one of three examples of say a C14 Cobb in PSA9 shape.
That card in their possession being jeopardized by say a PSA9 that may have some alteration of some sort and felt that perhaps a major grading card company may have let it go?
So SGC gives it a 96 and you look at it and perhaps see the formation of a wrinkle that disappered, then what? You give it a a quick downgrade? So now it's a 96/60?
As a person who refuses to pay $15K for a PSA9 Goudey common or even come close to that amount for anything, the service is meaningless to me. I think SGC does a magnificent job so why should I get a second opinion on a C14 Zach Wheat graded SGC30?
Or am I just completely off base here as this thread has so many various opinions that I think the original idea and it's honest contributions may be missed to me.
