I agree with @Coinfrog, the cleaning looks old, and it has retoned.
I'm more concerned with the more recent parallel scratches below the eagle's beak. A couple of those scratches are fairly deep, and they are noticeable. IMHO, the old cleaning wouldn't detail the coin, but the scratches likely drop-grade it a full point for eye appeal.
Just in terms of technical grade, this would be an "AU slider," what eventually will become EF-48. I think it takes a hit to EF-45 (or EF-40 on a really bad day) for eye appeal if it straight grades.
