For some reason, this little silver obol from Massalia has really gone to town with the toning in the three years it's sat in my coin cabinet. It was essentially stripped when I bought it, and now it's quite a colorful little piece. I like it. There are a few other silver coins that have developed hints of iridescent toning after sitting in my cabinet for a couple years, but nothing like this coin! Let me know what you think.
