The light give the appearance of a stacking bend or similar parallel to the spine. Looks pressable. 8ish as is, low 9s pressed. The CW is that grading fees can't be recouped easily unless you end up with a 9.8 or 9.6. A raw advertised 9.0/9.2 sold on ebay in Nov for $130, it does not look NM. I'd guestimate a raw in this condition would sell for $150-200. A CGC 9.0/9.2 goes for around $300 right now. Grading/shipping/pressing is going to be in the vicinity of $100 for a Vintage book. Could be a modest profit for grading, might break even, and it's going to take 30-60 days from the time you post it to CGC to get it back (if their turnaround time is accurate).
