Yes, they can tone in slabs.
Slabs are not airtight so storage conditions can affect them.
A serious case is when coins have gone through nasty weather such as hurricanes.
High moisture/humidity; no A/C because of power loss; even submerged in flood water.
I have never seen a coin tone drastically in a modern NGC slab, unless there was some serious help from a nefarious person.
What we see on this coin is classic mint set toning, not a gassed slab.
That's what I was wondering about myself. Photo enhancement
There could be some photoshop enhancement. But that is not the case here. The last four photos were taken to show the beauty and tone of the coin when the first were not. NGC takes photos on a basic set up, this sometimes shows the toning sometimes it does not.
I've noticed this before. I've also noticed their pictures being real dark sometimes. Sometimes I've bought a coin based on the tpg picture over the sellers picture. It appears that brighter lights were used on the ngc photo.
I agree completely on the FBL. Not sure which one but one of the top 2 TPGS only considers the bottom bell lines.
IIRC, NGC requires both upper and lower, and PCGS only requires lower.
I know that sometimes planchet flaws are accepted, That mark that crosses two of the upper lines does not look like a flaw. And should have kept it from the designation.
