How Bad Will Rim Dings Affect Grading?

UPDATE:

1881-s Ms 62
1884-o Ms 64
1897 Ms 62

Looks like they take off 1-2 points for minor dings. Good to know for future purchases

Hello

Not sure if this appropriate for me to add a coin here for assessment.

I have a 1966 Kennedy half I am fairly sure is a business strike. I don't have a means to post very good pictures but hopefully these will help. The coin has never until now been protected, its dirty but looks to be MS with only minor imperfections. Minor, except for the rim damage on the obverse side to the left of (IN GOD WE TRUST).
Will this coin straight grade or not? What would it grade without the rim damage?

Thank you
