This is a follow up question to my chances of getting a sticker at CAC. Our hosts did a very professional job of removing the PVC (seen at the top of hair as white) from my Buffalo Nickel. However the appearance changed from lustrous original gold color tone to incredible lustrous new as minted look. Did this hurt, help, or neither the appearance and desire-ability and market acceptance of this coin. No idea if PCGS used acetone or something completely different, or because of the nickel metal the toning somehow dissolved. Reposting pictures for newcomers. Thanks for your feedback.

Looks like the coin may have been etched for that swath to still be visible. Any Trueview pictures? This is a Gold Shield coin.
Just because PCGS graded the coin doesn't mean it wasn't damaged from exposure to PVC residue.
I suggest you get a hold of a good stereoscope or a dealer who has one, examine the coin, and if you see any etching (which is likely, IMO, then sell it and get another coin if you want a CAC sticker that badly.
Looks as if it will get a sticker.... Let us know how it goes... Cheers, RickO
What does etched mean?
Did you really need to start yet another thread related to this coin? I think this is thread number five on this forum.

Give him a break. This might be the only decent coin that he owns.

Etching is when some of the coin is eaten away but the PVC it will eat away a tiny bit as it sits on a coin. This is why you need to get it removed ASAP. But if left to long it can totally destroyed a coins look.
Hoard the keys.
Etched means to corrode or "eat away" at the surface. Acids eat away at the coin's surface until it creates first a matte-like or sandblasted surface to a microporous or porous surface.
Expand and explore the Trueview of this coin that recently was straight-graded by our host. TPGs will allow some light etching on a well-circulated coin but less so in higher grades. If this etching and pitting become too extensive, it's considered "details" - environmental damage" or "97" for their numerical grade. The second picture shows an ungraded coin with a more extensively corroded surface (from Bugert, 2009).
