These haven't been sold at auction in the past 3 years. It might be a gamble as a 64 that PCGS values at 110 sold for 36$ you would need the 65 or 66 in order to recoup your grading costs. Do you plan on selling it? Or, do you just want it protected?
Make sure that isn't rub on the cheek ear and upper hair. If so you would be over paying to have it attributed and graded. I sold 5 low MS 71d's last summer for about 20 each. A collector will know what he is looking especially with the photos you took. @atrox001
