Thanks for the interesting info.

I've only submitted coins and medals to NGC because I don't want to pay for membership to more than 1 grading firm and NGC has, in my view, done a good job for me.

The 1 thing that PCGS may currently have going better than NGC (but that will likely change) is PCGS's virtually air tight holders. For preservation over the long term, this seems to be a big plus.....though I do wonder how long the actual plastic of the holders remains viable before it starts to decay, crack, and disintegrate.

Aren't PCGS's slabs supposed to the more problematic ones or have they introduced better quality slabs? Just asking for clarification.

For modern Chinese gold and silver PCGS slab cause coins to tone faster and make them very unattractive.  Maybe the airtight holders trap the contamination and destroy coins quicker than if the holder allowed the coins to breathe.
