Anyone use one of these?

Not yet, but I need to find some good PCGS slab holders - I don't care much for the standard blue ones, and I came across an enormous aluminum suitcase that seemed like overkill for my small collection. Where did you find that?

 

No, I think it was Doug who said wood gives off gases.

 

Is that wood?

 

Only certain woods give off harmful gasses, particularly pine.

 

You give off gases!

 

If the wood was sealed with polyurethane or something, would the gas still come through?

 

Post #8 polyurethane

I don't know. How could you test it, on your own, to find out?

 

Very true. Especially if one considers toning to be damage.

 

Wood out gassing determines ( other than species), whether it was kiln dried, time after cutting, temperature exposed to, humidity exposed to, etc. Freshly cut moist wood will outgas much more than older, kiln dried wood. The wood doesn't continue to make fresh product, so is similar to PVC plastic, once the plasticizers outgas, the plastic itself is less of a problem. One way is to close your eyes and smell the wood. Freshly cut oak for example has a very strong smell, some of my 20+ year old stock does not ( and is harder than heck).

 

It is one thing that unites canines and male humans, the older they get, the gassier they get.:devil:

 

Still trying to figure out how to AT coins?

 

You devil Ken. Good to see ya. Where the heck ya been?

 

I would worry that the polyurethane would also put off gases. I don't feel there is anything that's 100% safe.

 

Nope.

 

Set it on the bathroom vanity and rip some gas out on it.

 

Not disagreeing with you, but could you show me what the "terminal stage" looks like?
