I have a coin collection that are in NGC slabs. I'm interested in storing these slabs in a wooden case that holds approximately 30 slabs. Most of the slab holders I have seen are made for PCGS, which are smaller than the NGC slabs. I'm also looking for something which isn't very expensive. Any photos /suggestions / links? Thank you
A far as storing coins , an affordable protection is aluminum storage boxes . They minimize inside temperature fluctuations far better than any of those molded plastic or wooden boxes, for one reason. Durability is another factor .
I haven't seen them. Most of those plastic boxes are made in china and who knows what is emitting from them . I use my Aluminum ( made in the USA ) boxes.

If you don't know what's in them, then there's also no reason to AGAIN stoop to blaming the Chinese just because you have an open bias towards that group of people.
Do Not store your coins, including slabbed coins, in wood cases. There are a number of times this has been discussed and explained. Do a search for it if you need more info on the harm wood storage devices can do to your coins. Instead, find an inert material as suggested or consult NGC for a recommendation. The NGC slab storage boxes and Intercept Shield cases are suitable. edit: To add this link about harms of wood storage cases: Coin Displays
Make sure you buy the right holder for the right TPG some are not interchangeable, Ive got A modern "Blue Box"from Whitman that only allows PCGS slabs, NGC,s will not fit! so make Sure you specify before you buy!
The aluminum boxes are sized for PCGS<NGC<ANACS>ICG The SAFE products are made in Germany and are truly excellent sturdy cointainers . They make some very good products for coin collections.
Wood Cases Don't discount wood cases all together - you just have to be wary of the type of wood that is used. Mahogany is best known and proven as a wood that does not contain any harmul gases that would effect coins. There have been many articles published on this topic in coin magazines. Just make sure you know the source of the wood.
The lesser of evils still isn't free of risks, especially if those hardwoods have been treated in any way to stablize them unnaturally. I wouldn't trust any wood I couldn't verify the purity of oils or other finishes that can over time present problems to valuables. Certain finishing products can gas-off or leach out of the wood effecting the atmosphere around the items stored within. It's so much easier and safer to remove such risks by avoiding wood all together when there are inert options available.
It's not that mahogany doesn't put off any gases, it just puts off less gas than other woods. So if one is bound and determined to use wood, mahogany is the best of a group of bad choices. The best choice is not to use wood at all.
Who makes some slab cases that are Made in USA? I prefer ones that do not grip the slab too tight but just enough to keep it from rattling.
Those aluminum cases look really nice! Never seen one before. Personally, I use the Intercept shield slab covers and the accompanying Intercept box that those come in. I have several of them and need to buy more. The wood boxes look nice for presentation but how many times are you going to leave something out presenting it? I would also wonder if it would depend on the coin for using a wood holder? Do any gases from a wood holder affect a circulated coin much? How about a gold coin? A circulated gold coin? If so what would it to do them? I agree that wood looks nice but is less than ideal for a long term storage option. The aluminum or Intercept boxes seem like the way to go.
