Nice tone and I would definitely keep it but somehow I have a feeling it could very well be AT. The reason I would suggest that is because it's very similar on both sides almost as it was planned to be that way. On the reverse and obverse only the center fields are toned with the highest areas toned very similar in color and the rest of the field and rim another color. I do see a small area on the reverse that seems not to be affected by the toning. Still it's a nice looking coin...interesting for sure.
