Found this Ike in amonst some others in a box that was in storage. I thought it was weird to be black, then it dawned on me that it is a silver one. Sure enough, s mint mark. I never realized what it was. I got it in change somewhere many moons ago and put it with some other clad ones. Gave it a bath in some acetone, but that's it. Thought about maybe dipping it, but..... Figured I'd post about it, since I know nothing about the varieties of the Ike dollars. Is there anything special about this one?
