Let's discuss this. What makes a coin AT? Must it be intentional?
I bought this maple leaf from a part time dealer I know. He said he got the coin from someone who took it from a roll and since he didn't have a flip, he put it in a leather pouch. The guy I know forgot about the coin for a few years and found it recently. Took it out, and the coin is as imaged. Is this AT?

Let's discuss this. What makes a coin AT? Must it be intentional?
Here's my definition of AT (and it's only my opinion, not some standard). Others please feel free to disagree.
If a coin is toned from exposing it to an environment that accelerates oxidation, then the coin is artificially toned.
Since intent can not be measured, one has only the coin to use as a gauge: evenness of toning and time to tone.
Given the normal reaction rate of tarnishing in absence of accelerants, it should take years under normal conditions for the coin to come to that state.
I have seen how quickly coins tone in a leather environment. I forgot about some BU bronze bits that I had put in my briefcase while on a trip to London and Ireland. A year later, I found them - the toning was very pronouced.
As a cleaner of "Ancient Romans" I have seen what happens to copper, bronze and silver when different chemicals are used on them. Even "american tap-water" can artificially tone a coin.
"MY" definition of AT - the deliberate or accidental cause: by chemical, laser, heat, to alter a coin. NT - natural occurance due to enviromental factors, time, proper or improper storage.
I would say your coin is Naturally Toned, I have several that look similar but not quite as striking.
Technically speaking ANY toning is a sign of chemical oxidation/reaction to the base metal of the coin and therefore ALL toned coins are "AT" because they were not manufactured that way.
By current standards AT is deliberately "artifical".

Yep, it was originally ATed.

Don, a 68 is never irrelevant, especially if you ever decide to sell it.
