PCGS wood boxes for slabs

I recently got a couple of the one that holds 30 slabs. Looks very nice and the slabs are contained "just right". The boxes are solidly contructed. Best guess is they are made from oak. Impressive from a basic furniture point of view. Definitely classy and a good way to display a collection in an elegant, yet understated way.

Hi all,
is is quite true that wood releases acidic vapors as it ages - this is called "outgassing" and oak is the worst offender in this respect (also, oak remains terribly hygroscopic even AFTER seasoning - a single block of "green" white oak 4' x 4 1/2" x 4 1/2" can hold 31.5 gallons of water! That is 262 pounds!) . I will not hazard a guess what cherrywood or cherry finish/varnish will do. This usually comes up in framing valuable works of art in wood frames. Countless works of art and prints have been damaged from outgassing. Unless this issue has been addressed or resolved and we don't know it, my solution (C) for the PCGS Storage Box is to liberally coat the inside surfaces of the storage boxes with an acrylic "gesso" (not true gesso which is slaked plaster of Paris in hide glue) - the CaCo2 in an acrylic emulsion will act as a neutralizing buffer. It could be black in color and serve it's purpose under the velvet material (compositon unknown?). These gasses damage paper and fabric; I wonder what the effect on the various coin metals will be, let alone the delicate surfaces of a proof copper coin. As I read that PCGS slabs are not hermetically sealed I will never know. I would not put my coins in anything made of wood. People talk about slabbed coins toning "all by themselves" (especially in NGC holders I think I read) - if this is happening on its own from "regular" exposure or storage why expedite the process by storing coins in a concentrated organic acidic environment - such as the PCGS box inside a deposit box?

Hi there, thought this might be on interest. I have no further information about the boxes or slabs - but I did see a post just yesterday about PCGS slabbed Proof coins "turning" once in the holder. I sent a letter to PCGS Q&A but did receive any sort of reply. Perhaps they are fully aware of this since design and there is no issue as it was addressed - perhaps they are totally unaware of it and these hygroscopic organic boxes stored in a dark contained location like a deposit box is a very, very bad place to store your coins. I will err on the side of safety.

Hi,
I don't understand what you mean - please restate?
Thanks,

I mean, if you took the sheets of anticorosive protectorant out of say the specialized Amos boxes or some select Intercept shield boxes and inlayed them in the PCGS wooden boxes, would they solve the potential problems you suggested?
Hope this helps.
