So I recently bought a 1881 Morgan dollar
MS63 the coin looks amazing on the front but when you flip it over it has a black spot on the wreath, my main question is how does this happen? And why in just a little spot? Thanks in advance for yalls help, I'm kinda new so I don't know all the bells and whistles work yet.
I'm just curious why does it just why does it make a spot in that area, how come it isn't in a different area?
