Have been going through my change for a few years now, but only last few months have I started looking for stamping errors, double dies, and such. A few days ago while giving my a change a quick once over, I saw this dime. 1985 D Is this a stamping error or does anyone have an idea what it is? The back has the same thing but just less pronounced. I tried to get best pics I could. Any help would be greatly appreciated and I can get you pics from angles or with more/less lighting if need be.
