I don't think toning should be taking into consideration in grading because everyone has a different opinion of whether a given amoutn or type of toning is attractive or not. I have seen people rave over similar toning on US coin from the old double mint sets. Bas the grade on wear and marks. If you think the toning is nice pay more for the coin. If not pay less or pass. But don't raise or lower the grade because someone like the color.
