You are correct they were very strick in the green label days, My first grade was a 65 then I second guessed myself and changed it. I think its a beautiful coin and deserves the grade, alot of the green labels are canditates for upgrades but not all are, thats how the green label became so popular with collectors/investors because they could buy a coin labeled MS-65 and resubmit it and it come back a MS-66 which in some coins is big money
