Grading Scale, Grading Standards, and the Economy

Here is the best information that Graded Comic Books can give to anyone considering getting their comic books certified by a 3rd party comic book grading company.
If you are looking to sell graded comic books:
The certification of a 3rd party grader like the Certified Guaranty Corporation ( CGC ) or Professional Grading eXperts ( PGX ) can help give buyers who don’t know you the confidence that they are getting the grade for which they are paying. It can also help when consigning the comic book to a company like which will only charge you a 10% commission to scan, list, market and sell your PGX and CGC graded comic books.
Make sure you really understanding graded comic books before paying to have them “slabbed” by CGC or PGX.  Not every old Golden Age or Silver Age comic book is worth more than a few bucks. If you spend $32 plus $18 shipping back and forth to have a 12 cent Amazing Spiderman comic book that “looks pretty good for how old it is” come back as a 2.0 Good on the 10 point grading scale, depending on the comic book issue number, that comic book may only sell for $20 - $25. You just lost $25 - $30 instead of making money!  In all likelihood, that Good 2.0 comic book would have sold for the same price regardless of the slabbing.
Other times, it makes sense to have comic books graded by CGC or PGX.  If the difference in value between a 9.2 Near Mint Minus and 9.4 Near Mint is several hundred dollars, or even several thousand, and you’re confident that you know enough about grading where it will at least get a 9.2 and not an 8.0 where the price difference is much less, than go ahead and do get graded comic books.
If you don’t know whether or not it is cost effective to get your comic books graded, contact for a free appraisal. Since they want your comics for consignment, and their 10% commission is tied to your 90% net profit, their interests are tied to your in giving you an honest and objective evaluation, and their staff will be happy to guide you through the ins and outs of the comic book certification process.
If you’re looking to buy graded comic books:
To a small extent, grading is subjective, and even the professionals at CGC and PGX may grade the exact same comic differently on a different day. There is also no law against cracking a comic out of the holder so you can touch, smell, feel – and even read, the comic book after you’ve bought it.
A good place to buy graded comic books is Their founder created the 10 point grading scale that is used today by CGC, PGX and industry wide.  Metropolis Comics sells CGC and PGX graded comic books, as well comic books professionally graded by their experts (not in a plastic slab – bagged and boarded). Metropolis’ advice to collectors is that they should be happy with the comic books they put into their collection, and if the grade by CGC is the make or break of whether or not they can be happy with their purchase, those collectors should only buy CGC comics. Metropolis is known for their strict grading, and sometimes comics purchased from them come back with higher grades from CGC, other times, slightly lower grades, and very often, exactly the same.
What if, in your vintage comic book collection, you have a Amazing Spider-Man #68, 1969. A Near Mint / Mint 9.8 certified copy may fetch upwards of $4,000. A hefty sum! But if the copy was Near Mint Plus, 9.6 graded, you may find it selling for only $385.

If that very same Amazing Spider-Man #68 lacked the freshness of a brand new book, sporting sharp, fine edges, a glossy, tight cover, and without even the lightest crease, then it may be appraised and encased in a 6.0 Fine holder, with a $20 retail value. It's hard to justify spending the $50 grading fee to end up with a $20 comic book!

Accurate comic book assessment requires the trained eye of a professional, and it can be difficult for even the most enthusiastic collector to objectively appraise the condition, page quality, and pedigree of his collection in order to determine the grade and market value his books would fetch at auction.
