Eagle looks really flatly struck. And the pics don't show the luster well. Just answering your question, the slab grade looks in the ballpark to me.
It’s a weak strike with a couple hits and bag marks in prime focal areas. It might be a nice for a MS63, but overall I think it is graded fairly.
It looks like a Mint State counterfeit to me. The 1883-CC dollar comes well struck, and the luster on this thing looks wrong. Here is an example that I won for an exhibit at the FUN Show. This is typical for the issue.
There are some poorly struck examples of the 83-CC Morgan (a couple of PCGS examples below) so one should be careful about dismissing poorly detailed coins off the cuff, however, this is unquestionably a fake, with fatty letters and rounded tips of stars.
Look at the stars, especially obverse. Look at the denticles, especially obverse. Look under the O and L in DOLLAR. This isn't a VAM, it's a CAM (Chinese Amateur Mockery). Edit: and seeing that @Jack D. Young started this thread before I even made my post here, I'm feeling a bit like our old friend Mr. Ed Wood right now...
It's not just the eagles breast that is weak, it's head and lower body don't look struck up either... I don't think this coin shows wear, but it is a not very convincing fake. I reckon most of us assume that anything the OP posts is related to the very good job he does at searching out fakes. Though I'm not sure if he truly wanted a grade opinion or not lol.
Now that is really lazy on the part of the Chinese slab counterfeiters. There are many 1883-CC dollar serial codes that they could have used.
Thanks @longshot ; actually I am interested in thoughts on the grade, as the counterfeiters often miss the mark there as well...
