1971-D KHD - Educational Purposes - Grading Thoughts

Attemtping to educate myself on the varying aspects of grading in the MS level, I feel fairly confident in calling out circulated grades however have little in the MS space.

I think this KHD is a perfect example to work with; uninterrupted luster, great eye appeal (to me), and for the most part it is issue free.

Starting with the Reverse since I think it near flawless
- one insignificant rim ding at 0830, another stronger one at 1300, little scuff center shield, no bag marks
- I'd grade the Reverse at 66. I think the strike is somewhat weak around the eagle however looking at other 71-Ds, it appears common so no adjustment needed. Reverse at 66.

Obverse
- no rim hits, few minor bag marks. Abrasion at 1400 rim line and another mid-neck.
- I'd grade the Obverse at 65. Again, I find the strike weak but common with 71-Ds, no adjustment needed. Obverse at 65.

So does this average out at a 65+ or does it lowest common at 65? Do rim dings carry more weight than I give them?

Or should I re-read Grading Coins for Dummies. No need to be kind, brutal honesty will help me immensely.
