66. Looks like heavy tab toning. Central toning on boat side is quite attractive, but there's a lot of terminal or near-terminal toning on it. Toning can hide a lot of surface defects, and so does the Norfolk design, but it's not hiding the really bright (fresh?) one in the middle of the scepter.
This is one I'd want to rotate around and see how much luster there might be through the toning. But from the pictures I'd go 66.

I think the CAC absolutely helps it. PCGS Census: 68 = 212 68+ = 15 69 = 3 NGC Census: 68 = 100 68 + = 7 68 * = 16 68+* = 3 69 = 1 I believe this slab is prior to the star designation with NGC. With it earning a CAC in 68 it’s obviously at the top end of the grade 68. I think the numbers in the census prove without a doubt the sticker adds value. At the very least this coin is within a sample of the top 22 out of about 312 coins graded at that level. I think the coin is actually a 68*+ making it one of what would be 4. This is the type of coin you see down the road that ends up grading 69* and becomes a top pop and then somehow earns a CAC and hits auction and brings solid 5 figures and everybody who previously owned it gets burned at money left on the table.
