1880 S/ DMPL Rainbow Toned

I think with AT they would have done the entire coin not just that one edge.

I bought a common-date, DMPL Morgan once that had symmetrical, colorful toning crescents on both sides. I later resold it and the buyer eventually decided it had been whizzed, then artificially toned. I wasn't completely sure but he did share some detailed photos that confirmed some kind of surface alteration had been performed. I offered his money back but he decided to hang onto it.

My coin was actually brighter-colored than this 1880-S. Personally I find its color too dark to be attractive and the half-moon tone pattern on the obverse is rather odd. All in all, based on my previous questionable purchase I would not buy this 1880-S, even for $90. I also would not invest a grading fee, but if you choose to take a chance maybe it will work out. Good luck!
