I know that this is a BIG no no for most coins. But it's not a rare date, it's not in that good of condition and it looks like it came out of the ground. Is there any way to clean it up a little bit without damaging it any further?
I was thinking just a soak in some warm water then patting it dry should clean it up a bit but I'm guessing that it's stuck on a little tougher than that.
Any help or suggestions would be greatly appreciated, thanks.
