Beautiful coin! I believe the green "spot" was the result of prolonged contact with another coin with a high copper composition which resulted in a Cu oxidation "stain".
As for effecting the grade, I would suspect the distracting "ding" between the right upper leaves would take away more than the "spot". Just my humble opinion.
Nice Mint State coin nonetheless!
