I don't think so, what do you think? I've bought from the seller before and he's always been spot on as a seller but... These Walkers don't look like natural toning to me at all. The reverses don't show anything at all, what do you think? https://www.ebay.com/sch/centsles/m...2O0AAOSwzypgNVAq&rt=nc&_trksid=p2047675.l2562
Put into a folder years ago and many times this is the toning that forms. Reverse has no toning since no air got to it, and the obverse is reacting to the sulphur in the cardboard. If there had been more humidity the toning on the obverse would have been more widespread. I have pulled many, many such coins out of old folders sir. I see nothing unusual about it. It might have been dipped before placed in the folder, which is another reason the coin did not tone more.
That coin looks to have been stripped and polished down to that awful white. It looks like someone was attempting to artificially tone the coin, but it turned. I'll bet when the chemicals were applied, it was bright and unnatural blue or red. Now its that funky dark color. I'd avoid this.
Many of the seller's listings have Obverse toning that looks like a smaller coin was placed on the center, then blowtorched.
I don't buy anything raw from that seller, too much of a crapshoot. That's saying a lot, since about half my collection was purchased via eBay.
Could be possible especially if placed in a folder for years as I've never placed any in a folder to tone at all, so idk. It's been years since I've bought a Toner on the bay anyways and I'm okay to stay away.
If stripped, I don't see why it would have a ring retone. Like I said, overly dipped coins will not want to tone, but can be forced to, and will do so mostly where exposure is happening. I still would place my money on dipped coin placed in an old coin folder if it was my bet. Nice, lustrous BU surfaces may have toned around the edges this dark, but there should have been pretty colors in the middle, normal gradation patterns.
Overly dipped coins won't retone in a natural manner unless forced. That's the gist of your post. My feeling is, some chemicals were applied to artificially tone this coin, and then it turned. This is not a natural look. Folder toning tends to happen on both sides, since the entire coin is in contact with the folder. I have never in my life seen one sided natural ring toning like this coin appears to display. It just isn't natural.
