I just picked up a great collection of about 100 Morgan and Peace dollars and here are some of the better dates and conditions. Was curious if any of these would elevate to the MS64 or 65 level when the value really gets going. Enjoy!
84CC - there are some really deep gashes in her cheek. I'd have a hard time seeing this as a 64. The reverse is clean though. This is the classic split grade - 63 obverse, 65 reverse. Unfortunately, the obverse usually dominates. 83CC - (why did you list the pictures out of order!) I like this one a lot better... except for the spot in front of her nose. Much less severe marks. I'd call this one a good shot at a 64, unless the pictures are hiding something. Reverse is semi-prooflike which is nice. 1903O - I think this is the highest grade of the lot. I think it is clearly 64.
