No bean. the 59-O is also known for light striking and this coin is particularly weak. I would call it a 64 but not an A or B coin and I don't think CAC will appreciate the toning particularly as it makes it difficult to judge the luster.
with the toning I can't really judge luster or surface marks, so I will flip a coin and guess... no bean.
Are you going to post results on this one @ToughCOINS ? Or am I missing something? I'm at 6 correct out of 14. CAC was tough on some nice coins IMO.
