Is my coin AT, and if so, what method was used?

But only because the colors are vaguely similar
Pharmer what does the reverse look like?
Edited to explain that I don't have it here, it's at work. I imaged the obverse and uploaded that the other day.

Then odds are that it's NT.

In all honesty I wouldnt care either way, its a cool looking coin
we all know you have NO A.T coins , nor do you know how to tone them yourself.
We , the people , know as well that you will not believe a coin is A.T`d unless
it were proven to you in a court of law .

Yeah, I think Pharmer's coin is probably NT too. All I did was look through my AT examples at Link to AT examples and the Sac was the closest match. The Sac was done with a chemical that tends to result in purplish-blue.

Actually, proving it to me in a chem lab would suffice.
You made me smile again, Michael.
A gentleman with a chemistry background pm'd with a suggestion that it was exposed to a halogen gas. NOW we are getting somewhere! Someone has finally suggested a mechanism. I think halogen gases include chlorine, fluorine, deceptorine, right? I bet it wouldn't be too hard to find a source of chlorine gas.
