Ok, first attempt at posting a photo didn't go so well.
I want to thank everyone for their input and their help, I do believe it's altered as well and I'm almost tempted to try to scrape it to see if I can get it to peel at it's edge. I did a magnet test and it pushes the coin away instead of sticking to it which is odd because silver is non-magnetic but conductive, either the magnet or the coin would have to have been charged for it to push I believe.
