How long do I have with slabbed 20th aniv. set (except proof) before the spots start showing up?

No but they certainly hurt the value when you go to sell them.

Now that's an understatement. Try strickly bullion value. Take it from someone who's tried to sell milk spotted coins. It's like the lepers of old. No one wants to touch 'em.

This is interesting and something I've noticed as well. I have about a dozen ASEs sitting in a drawer in flips and none have developed spots. A couple are as old as 1986. Could slabbing itself be causing these spots somehow?
My icon IS my coin. It is a gem 1949 FBL Franklin.

Does anyone know how this thread was resolved, if it ever was? It seems like PCGS was willing to live up to the grade guarantee but only after every coin in question was first downgraded. David Hall provides a reply but does not address the grading issue mentioned by wondercoin.

Some people have been concerned about the chemicals used to make the plastic surrounding the coin flexible. Could that be the cause?

If I may ask, how will they make it right?

I don't believe that there would be anything added to slabbing plastic to make it flexible. You must be confusing it with plasticizers such as di-nonyl phthalate which are added to PVC [which is brittle] in order to make it pliable.

Isn't the white plastic in the NGC slab flexible? What about the clear ring in the PCGS slab? I think that's what people were concerned about. I haven't cracked PCGS/NGC slabs myself to check yet but the impression I got was that the coin was snuggly held by the edge with those inner materials and those would have to be somewhat flexible to accomplish that? Maybe PCGS doesn't use inner rings for ASEs?

This might be possible especially if the chemical is the same as what is used for the AirTite rings. I have had milk spotting develop on coins that were not slabbed but kept in AirTites.
Edited to add: Actually, PCGS has a flexible insert that goes around the coin befor it is slabbed. This enables them to have one slab which covers most all coins.
The name is LEE!

There is a difference between being pliable and being flexible. A PCGS or NGC slab half will flex some if you bend or twist it slightly. I have never cracked a newer PCGS slab, but I'm told they all have an inner sealing ring which is most likely silicone, or polyurethane or maybe even polyethylene.
It would seem [based upon the practices of one/some members here] that the solution to the spotting problem would be to dip your ASE's BEFORE submitting or find some way to sweet talk PCGS into doing this for you. Its possible I suppose that there is some trace contaminant in the slab material itself [polymerization catalysts, etc.]
that aggravate the spotting problem to the point that it becomes visible. If that were true, spotting would always happen. Since it doesn't, it would seem to be a combination of the slab AND a poorly prepared/washed/rinsed planchet IMO.
