Nice high EF/AU maybe coin. It has some red and brown.
Depending on the percentage of red would need to be determined
in hand. Those cracks were pretty common back then. Most likely coin was rubbed a little clean along the way. Maybe from just normal handling. Who knows ? A blatant polishing etc. is pretty obvious on a lot of coins and also I still do believe that technically there are only a handful of coins that have not been cleaned in some form or manner. PCGS lately
has been all over the place with their grades etc. There should be one standard applied to all of the TPG
's/grading services period. Why are some detailed graded and stated and some not ? I.E.: VG details cleaned. Or like your coin. No grade, no color just cleaned ? Jeesh. That's a nice coin by the way. Cleaned or not. I'd crack it out and start over.
But not with PCGS.
