They are sealed but not 100% airtight. Environmental conditions such as water vapor (humidity) or sulfurous air can still cause toning.

Yes UV. Let a new quarter on sun light and become yellow

Ultra Violet light. Must have been something about the 2000s. I Have 6 sets that I bought about 15 years ago. They look just like this. Just looked at them, doesn't look like they toned any farther than they were when I bought them.

Could there be something in the paper or plastic ogp that is causing this? I've always been curious about this. I mean, it is sealed and more protected from environmental factors than your average coin in circulation, but then there's this fairly even golden toning.

Agreed, just some weird toning.
Errers and Varietys.

I rather like the gold cameo effect.
However, they need to be airtight sealed to keep them that way.

it does have a nice appearance if you are into toning of a silver coin.

oh, uv light. ok, yeah, they weren't in sunlight ever, that's why I didn't even think of that. lol. yeah, all the silver coins are toned, all of it is on the "rough" part. I have one with no toning, and one like this. I wonder if maybe they shipped some via air and the altitude popped the seal?

I have often wondered if this sort of toning is the result of cigarette smoking or actual house fire smoke.

I hate to admit it, but I've put coins on the roof during California forest fires and they tone gold. Maybe it's the UV, though. I figured it was the smoke in the air.
