Old cleaning, retoning from that. IMHO, it is market acceptable and straight grades. The obverse toning is a little blotchy, but not a distraction. There are quite a few contact marks in the obverse right field. light wear on the central devices. Nothing abnormal with the wear. I agree with AU-55, and a shot at AU-58 on a good day.
In terms of value, I don't have a feel for the RPD/DDR value. Setting aside the variety, I agree with the upthread comments that this coin seems quite a bit overpriced if it would take MS dollars to acquire it.
Depending on where it is for sale and what flexibility exists for making a deal, this may be one to approach the seller with a multiple contingency offer: submit to PCGS
, and you will pay X dollars for AU-55, Y for 58, and Z for UNC, assuming it straight grades, and split the cost of grading regardless.
