Well, the reason I ask, and I don't know a darn thing about Lincoln Cents or coppers in general, the feilds and surface seem to me to be uneven almost like a pitted surface, not smooth.
Many early Lincolns have an almost matte finish, very different from later years. Here's another. This one is also a 66RD. The '11 is a 65RD Lance.
Hey - that is why I asked. I thought, though, that the pattern because so close to the shoulder line, might be an indication of a problem. But I just don't know a thing abut Lincolns.
