@JasonKflo, I hope you don't mind some additional rambling thoughts here.
I can see the rub above the ear on the next to last photo. I still can't see corresponding evidence of actual circulation on the other high points of the obverse or reverse. That could suggest there is one other possibility. This could
have been rub from storage in a coin drawer. That wouldn't negate the effect of the rub, but it could explain the lack of evidence of circulation in some of the usual places. I agree with you on the re-toning, that it could be from an album.
This coin definitely has been dipped, and then mishandled (badly) after the dipping. That explains the distracting fingerprints.
Looking at this one in hindsight, I can see how the combination of the hair rub, old dipping, fingerprints, and toning could have netted a mid-AU grade. I still don't agree with that, but I can see it.
You asked about conservation. I think the prior dipping hurt the luster. There is luster in the last two photos, but it is blemished in areas by the dipping. Adding conservation to that could possibly
detail the coin. There isn't a lot of margin for error here, and I doubt that conservation could eliminate the harm from the oil on the fingerprints, anyway, and that's the biggest problem with appearance. The risk seems far too great for any possible reward.
As you noted, the slab is pretty scratched. That doesn't help the photos and may be a distraction for in-hand eye appeal.
There aren't a lot of choices here. I don't see PCGS
looking past the fingerprints and hair rub. That eliminates resubmission. I don't see a reason to risk conservation, and it wouldn't fix the fingerprint problem anyway. About the only things left are either a new slab from ANACS or ICG, and hoping for a slight bump to 55, or just springing it from its plastic jail and leaving it as a raw coin. With either of these options, if you go to sell the coin, a buyer may take a gamble, hoping for a higher grade.
Anyway, some final thoughts looking in the rearview mirror. My final thoughts plus fifty cents probably aren't even worth half a cup of day old convenience store coffee, though.
