"Raw" Prices vs. "Graded" Prices

I don't agree with this. Having a third party validate or confirm the quality of an item of value should always increase the price of that item, especially since the owner absorbed the cost (sometimes heavy) of getting the item valued. This is a common practice across other areas and is justifiable since we are not certified graders and can be biased. Also, the slab offers a degree of protection not offered by just a bag and board.

In my experience, it is is an extremely rare occurrence where a graded version of a book will go for the exact same price as its raw counterpart (unless the seller is intentionally going below guide to sell fast). If this site is going to take a position otherwise, then the price quoted on CPG just isn't based in reality or what's actually happening in the market.

Its possible that we might not be debating the same thing, but I'm not contending the existence of outliers. I'm challenging the accuracy of the reported values that I assume are supposed to be a reflection of the bell curve. It is possible that if some unlucky soul were to compile ALL market data and perform a comprehensive analysis then we may discover that the standard deviation is much larger than anyone would've anticipated. In the event of this "wild, wild west" scenario, we may be forced to challenge the whole enterprise of formal price guides in general. Regardless, I believe that a workable deviation exists and would have to conclude that most people do as well, otherwise we wouldn't be using/relying on these guides.

Hello,
This is my first post here. Can someone explain how CPG derives the prices for their graded comic listings?
