A Buffalo nickel that's toned nicely in the holder

The coin raw, and the color it's acquired since it came back from PCGS earlier this year. The coloring isn't much on the obverse, but the reverse is taking on some nice pink and gun-blue hues.

I've had the coin a couple of years. I submitted it first to NGC, didn't like the grade, so cracked it out and sent to PCGS. They graded it a bit more accurately, I think--meaning higher, of course. Nothing unusual about the storage, just sitting in a PCGS storage box in my office.
