What causes coins to turn in the slab?

We know PCGS withdrew their copper guarantee after copper turned in the slab... whether from coin doctoring or high temperature/humidity.
Aside from doctoring... what causes coins; copper, nickel, silver, gold, etc., to turn in the slab? If you store your coins in a closed environment with Taco Bell napkins, will the coins turn? If you place your slabs on the window sill, will the coins turn? If you store them in wood boxes, will the coins turn? If you store them with a high sulfuric cardboard, will the coins turn?
On the flipside... what prevents coins from turning in the slab? Will Intercept Shield prevent coins from toning? Will a SDB with desiccant prevent coins from turning?

In my opinion, intercept shields are only a temporizing measure. Think of them like sponges. Once their "pores" are saturated, the protection is gone. I've never seen any info on how long they are supposed to be effective in "normal" environments.

That's why PCGS has that little known organization - PCGS Men in Black.

Depend on how the cent was stored. That's why red copper in the older slab types are so popular. The presumtion is that the color must be stable after more than 10 years in the same slab.

Some slabs have very tiny people living in them. They have tiny horses and machines that they use to slowly turn coins inside the slabs.

I don't consider them tiny... I'd like to think of them as vertically challenged!

Now that was cerebral... or semantics!

...at least they won't support e.coli dangers.

IMO, 99 44/100% of red copper that's >120 years old has been messed with. Copper is a highly reactive metal. It doesn't stay bright and shiny in most circumstances.
The reason it turns after 15 years in a slab is it was dipped 15.1 years ago.
There is a dealer I've seen at shows who has an incredible number of bright red IHCs. Someone "in the know" told me he had perfected the dipping of copper.
P.S. Don't even think about asking.

IMO, 99 44/100% of silver coins are actually Ivory White and not Blast White!

Agree. I'm always skeptical when I see bright red copper or blast white silver more than 100 years old with the exception being Morgans that were stored in canvas bags for most of their life.

I see things going one of 2 ways
1) blast white/ bright red !
2) very colorful coins !
very little inbetween coins ?

Are you saying, that unless a coin was doctored, that coins don't tone in holders?
1) a poor rinse after a dip which may not turn until some time later.
2) silver and gold - the "haze", if not natural (and who knows what was accepted several years ago), may turn after a time. I know of an early gold coin which was "coated". The coating fell off the surface of the coin after it was sold through an innocent broker and hurt his credibility with the customer even after the TPG "made it right". I seem to recollect that this also happened on an MS66 14-D Saint that was bought by SWSNBN.
