Agreed on both

Yeah, I don't think it would bump any higher. I want to clean it just to make it present better, but only if it's not gonna drop in grade. I'm worried it's going to drop in grade. Even according to CGC 11 years ago marvel chipping didn't affect the grade as much as it does today.

Thinking about cracking this one, cleaning it and resubmitting. If I were to submit it today in the condition it's in now, do you think it would get a 6.0 again? Or would the marvel chipping ding the grade worse today than it did 11 years ago?

Thinking about having this book professionally deep cleaned and then resubmitting it to CGC. The book was originally graded and slabbed in 2012. I think if I were to crack it and resubmit it today, without the cleaning, with all the chipping it wouldn’t get the same grade. What are your thoughts on the chipping? From what I’ve read in CGC’s own official guide to grading, “marvel chipping” didn’t traditional affect grade too much, but today it’s viewed the same as any other missing piece. Do you think it will stay a 6.0 or is all the chipping gonna hit the grade hard?

When you say “moving” do you mean like Shaken Comic Syndrome? Or do you mean moving like “breathing” or settling? Like I said earlier I know that if not given room to expand and contract with temp and humidity changes framed prints will ripple in the same way as the fibers in the paper get stretched.

They were all graded between April and October of 2022. And I purchased each of them from different sources very shortly after they were slabbed. So it’s starting to look like pressings that have reverted to me.

I'm leaning more and more towards it not being related to the humidity inside my home. I looked at books I have displayed upstairs in my home where the RH is much higher around 60% and all of those books look fine. I did check the smart thermostat and it is displaying RH on the first floor as around 46%. I'm running at dehumidifier in the room with the books set at 45%. It seems to go down to 45 and then kick in again when it reaches 50%. I'm running a little experiment. I have one short box with Eva Dry Mini Dehumidifier (See Here) in the box and the another without. Both boxes have a Govee Hygrometer inside them and I'm checking the RH to see how it affects each box. I want to make sure I'm keeping the books at a consistent RH as well as not drying them out. What do you guys think? I've been storing them inside in the A/C without any humidity control for over a year and haven't had any issues (if the pics above were caused by humidity). Do you think I should continue to store them at the natural RH inside my house 45-50%? Or should I try continue to add the dehumidifier and mini dehumidifiers? The Govee is accurate to within +/- 3% RH, and the readings seem to swing up and down around 2% every hour. I think this is just accuracy of the readings and not and actual fluctuation. "Short Box 1" has the mini dehumidifier inside, and seems to be 1 to 2% lower than the box without.

I noticed what I thought was a humidity issue affecting some of my slabbed books (Read Here), I'm not so certain it is anymore, but it made me look at how I'm storing my books and if I'm storing and displaying them the best way possible. It was mentioned in the aforementioned thread that the Library of Congress recommends storing your books at 35% RH (relative humidity) (Read Here). I've also seen the American Library Association recommend between 30-40% RH (Read Here). BUT... I've also seen multiple posts on here where users recommend 40-50% RH, and acknowledge storing their own books around 50% RH. AND... CGC's own "The Official Guide to Grading Comics" says "the ideal humidity level is between 45 to 60 percent". So that's a lot of different opinions ranging from 30% on the low end all the way up to 60%. Each source also mentions that a "stable environment", even if not "ideal", is far more beneficial than an "ideal environment". In an effort to make sure I'm storing my books properly I don't want to end up using methods that cause too many fluctuations (a dehumidifier kicking on and off as RH rises and falls) or dries the books out to much (silica gel packs and mini dehumidifiers (See Here) in the boxes themselves) when leaving them at an RH% that my central A/C natural creates inside my home is ideal enough. So my question(s) to everyone is; What RH do store your books at? What do you believe is the ideal RH to store your books at? And finally, how do you control the RH where you store your books (i.e. dehumidifier, silica gel packs, mini dehumidifiers, dry cabinets, just inside an A/C'd part of my house)? Thanks!

I know from framing posters, if not given room to breath the paper will ripple just like this. So maybe the same affect is happening here inside the inner well.

Just got home and checked. It was 64% RH on the 2nd floor and 50% on the first floor where I keep the books. The 78% number I got from a smart thermostat which may have been showing me the chance of rain or RH outside. It’s just a dew drop with a percentage number. I assumed it was RH. I also went through some slabs that I know I’ve had longer and stored in the same place and conditions and they’re fine. So this may just be 3 examples of pressings reverting. Either way it gave me an opportunity to look at and address any storage issues. I put a dehumidifier in the room, along with some Eva dry mini dehumidifier’s (silica gel) in the actual short boxes. I also installed Bluetooth Govee hygrometers in each short box to monitor the RH inside the boxes to make sure the RH doesn’t get too high or too low.

edit: 50% RH where I store the books I keep them all inside the house in A/C. Except for that brief two days it was in the car while the house was treated (like I said probably a bad decision looking back). But the RH inside our house is very high. I’m not there now, but I think it’s around 78%. I know it’s over 70%.

It could be, but they all came from different sources.

I could see that if they were all from the same seller or collection. But I purchased two of these from two different eBay sellers and one from comiclink. Which makes me think it happened because of how I’m storing them. Granted every slab I have doesn’t look this, so … 🤷‍♂️

Yeap I’ve got some raws I was gonna send to be pressed and cleaned looks like I’ll be sending these slabs to cracked and pressed. Hey gives the opportunity to upgraded to a custom label. Gotta see the upsides

Exactly what I was thinking. No way these showed up and I wasn’t shocked. I would have remembered. I did remember that December last year we had a mold issue in the house and had to have the house “fogged” and I didn’t want the books sprayed. So I placed a few short boxes and these slabs in the car for two days. Again the raws are fine. But I think the slabs may have been affected because they have trapped cool air inside (like a camera lens or sunglasses that fog when you walk outside) that could have held moisture. No that I think about it, it wasn’t the smartest idea. But the crew was there and I didn’t know what to do with the books.
