Yes, I am wondering why nobody else bid on this coin, it looks good to me. I see light verdigris that can be addressed with Verdicare. I tend to avoid acetone with coppers even though I have used it on coppers and not have them discolor. I read this thing that acetone reacts with copper with the presence of light so it is best to soak it in the dark. Generally I think distilled water is best with coppers.
