Lehigh96, posted: "To be fair, he didn't say "placed" he said "dropped" in a shallow dip. The careless manner of inserting the coin in the dip could easily create a wave in the liquid yielding and uneven dip on the edge. [Nice theory but IMHO, very likely IMPOSSIBLE! Try it for yourself. You'll see.] Since the person dipping the coin only cared about removing the toning on the face, his carelessness of inserting the coin in the solution seems likely. PS, these are fun but wouldn't it be better to show us photos of the entire coin rather than just one small section. In this instance, I would very much like to see the "very colorful toning JOB."[Agree, that would have been educational for many; however, I suspect you know AT when you see it.] Anyway , I don't do entire coins, both sides, edges, holders or anything else unrelated to the characteristic I am showing because 99% of the time it is unnecessary!
^^^ This is what I was getting at. Toning was either being removed or being added, and the hard delineation made it look like it had been removed. I get the importance of the edge, but it is just one facet for determining what has happened to a coin.
I don't dip coins and I'm not purchasing dip for the purposes of proving or disproving this theory. You know more about the subject, I will take your word for it that it is impossible. And yes, I am very good at determining AT from NT, but I suspect that we have many members/lurkers who don't share the same level of confidence in that area that I do.
I have dipped a few coins before. IMO, EVERYONE who collects coins should know how to preserve them properly. Sometimes, that involves chemicals (PROPER CLEANING). The sharp line would not be present if a coin were dropped into the chemical. I have shown an AT coin above. There will be some NT/AT coins in future quizzes.
Paul...you could be totally right. My thought was it would be hard to place a coin in a shallow dip and remove it so quickly to get that kind of irregular pattern. It's not like coin dips are think in consistency. At least...that was my line of thinking.
A coin has 3 sides, in the pic we can only see one. The basic question was what can deduce from what we can see about how it got to be that way ? I think a few members hit on the idea when they suggested one side of the coin being treated with coin dip while the other side was not. The point that was not expressed however, but I think it was thought of, is that the 3rd side, the edge, suffered the consequences of that treatment resulting in its appearance. For what it's worth I was thinking along the same lines. The only part left open to question was the method used to apply the coin dip. Now like the old saying, 2 sides of the same coin. One side of the coin would be having color/toning removed from a toned coin, and the other side of the coin would be having color/toning color applied to a white coin. Either one could result in what we see in that picture. Insider was able to tell us which one it was, but only because he had the advantage of examining the entire coin. The question that still remains is what was the method of application ? Seeing the edge tells me it could not have been trying to dip one side of the only into a shallow bowl of coin dip, and the same thinking tells me it could not have been done that way with toning chemicals in the bowl either. Which kind of leaves us with the chemicals having been applied one way or another to only 1 side of the coin and small amount of those chemicals running partially down over the edge. What I'm trying to say is that those who expressed the idea of coin having had coin dip painted on, brushed on, maybe even wiped on, on only 1 side of the coin had the right idea. Only it wasn't coin dip being applied, it was toning chemicals. Like I said, 2 sides of the same coin, or if you prefer two sides of the same idea. Bottom line, trust your eyes and your thinking when only 1 thing seems to make sense. But don't forget to think outside the box while you're thinking. Because even though you've got how it happened right, you might not have why it happened right.
PS to all of you "purists" who don't like the way I do things.... Take a look at the stupid way my comment above is displayed. What did I write? You'll need to go to an extra step to find out.
...instead of after it like you're supposed to. Honest, using Reply does work better. It makes it easy for readers to tell what you're quoting vs. what you're saying, and it even gives a link (that little uparrow next to "said: ") that goes back to the original quoted post.

The simplest answer to what happened is the coin had a bad run-in with chemicals. Dip, bleach, Coin doc cocktail, I couldn't tell you.
