Quantity 1 available. Series Teenage Mutant Ninja Turtles. In an interview with Comictom, Matt Nelson head grader at CGC stated that they have tested leaving a slab in a tub of water and eventually the water made its sway in and ruined the comic book inside. A joke was made that if a slab were accidentally dunked into water and pulled back out like an Oreo cookie , it would probably be ok.
He also went on to say that it should be common sense, don't drop your book, don't leave it in direct light, don't leave it in a hot car and it will be fine. Perfect response! Use common sense! Ok, So why are the comic books not completely sealed inside? An article I found on the Library of Congress website gave a very good reason as to why paper products should not be sealed up air tight.
This acid hydrolysis reaction produces more acids, feeding further, continued degradation. CGC adds a sheet of microchamber paper to the front and back inside covers of every comic book they encapsulate to help absorb those acids that are constantly being released from our comics, so then why can't they be sealed tight to keep the outside air pollutants and moisture from seeping in?
Well, in a communication I had with a representative from the company that supplies the microchamber paper to CGC, her response to the question of completely sealing any paper product in a sleeve even with microchamber paper , was just awesome,. Further to that, the chemicals may not all remain just as they are when released. That is to say, if by-product of deterioration A and B are both released, there is a concern that they will combine and form chemical AB, which may cause even further issues.
Essentially all paper materials have a moisture content and sealed moisture along with the acids from the the paper and ink may in some cases accelerate the degradation of the paper. Interleaving paper, or "microchamber" paper that CGC adds to the inside of the books is designed to absorb some of the acids released by the paper in the comics, however if sealed air tight it could result in deterioration as well.
No, CGC Cases have no built in protection form damaging UV rays that could fade or deteriorate the comic, magazine or art inside. I mean that would be just another level of added protection for the comic inside, correct? Well, here is a couple things to think about, although slight, adding a UV inhibitor to the SAN Copolymer mixture will affect the clarity of the plastic, taking a small step backwards from one of their goals.
Referring to the most current revisions, or Generation of cases only, CGC uses three sizes of cases for encapsulating comic books and two different sizes for magazines or large format comics. It is also worth noting that they have several sizes of slabs to hold single page original art, 11"x17" and 9"x12" for sure, but I am quite certain there are other sizes as well. But again for interest of this article we will only focus on the five main sizes primarily used in the comic book industry.
According to CGC they are broken into two groups, "comic book size" and "magazine size". These groups are designated by the overall width and height of the case, then broken down from there by the thickness of the case and subsequent thickness of book each will hold. Preview books or ashcan books are good examples. On the small size the back half of the outer well of the slab is actually indented, or sunken in. What this does is actually create a thinner dimension on the inside of the case where the comic book mounts, thus it it used for thinner books.
The medium size case does not have this sunken in back, it is much more flush, creating more space inside the case for a thicker book. Depending on page weight and cover stock. There have been numerous forum and facebook posts about someone submitting a standard sized modern book with the typical pages and it will come back in a thick Golden Age slab. I have even seen a couple forum posts where already graded books were sent in for re-slabbing or re-grading in a standard sized slab, only to have it come back in a thick slab, or vice-versa.
The plastic flap sometimes used either along the spine or bottom edge of the comic book is simply put in place when needed to keep the book from shifting or moving inside the slab.
Having a more durable case would mean sacrificing those other qualities. Yes, but not without damaging the case and therefor rendering the grade and any certified signatures or markings on the book if applicable invalid. Unless done by or in the presence of and authorized CGC representative. Here are a few scenarios in which you may want to open your slab and remove your comic but still want to preserve certain characteristics about the book. On a side note to this scenario, if you are reholdering due to a damaged case, if the case is broken or separated to the point that the comic book can be removed, the comic will be regraded.
So that's it! I hope this information helps to answer some of the questions you may have had regarding your CGC cases. If you are looking for answers to questions I missed in this article I would love to hear them and I will do my best to track down the answers for you!
