After enlarging the obverse 300% I see something which looks familiar. On the high points of the hair line between the eye and ear I 'think' I can see 2 micro bubbles. Tiny air bubbles form on wax castings when they are 'invested' in the plaster used to make the mold. A vibrator is used to dislodge them before the plaster dries. A few micro bubbles will always remain on the finished cast and appear as "pimples" on the surface. They are usually removed by polishing.
A worn coin (esp.silver) should have smooth high points and fields unless corrosion has affected the surfaces. Polishing usually indicates someone had a need to hide something although I have seen "next of kin" do horrible things to coins before they take them to sell at the local 'coin shop'.
While I am unable to say with 100% certainty without better pics ...... This one looks like it may be ...... NFG 69. I say that with reluctance as I know it is painful to hear.
I hope I am wrong
Later on today I will try to find some of my uniface castings which I made when I was young (and handsome too !) to better illustrate my points.
