I'm not a Kennedy collector but this coin certainly looks like it should have graded as you suggest. Nice looking coin.
Tick in the field in front of his nose, tick on his cheek, tick in the field between TY, tick on the reverse to the right of the eagle, spot between stars under CA, pretty big tick on the rim under Half. 69 is the right grade, no chance of 70.
The lighting is making it really hard to see the DCAM, but I certainly see the reflective fields, and I don't see specular reflections on the devices, so I guess it's just a contrast issue.
