Makes sense it'd be cleaned, too much surface wear to be as shiny clean as it was. I agree with you guys it's most likely cleaned but I have no idea how, and judging off of the 2x2 it was in it had at least been in that 2x2 for long enough the white color was turning dirty white-grey.
Thanks for the extra replies on grade as well everyone! I am in no way a coin grader, PCGS has a good photo grade set up but I always have a hard time concluding anything for myself .
