From the quality of your images, I am assuming that they are scans correct? Scans do not show luster so they are not always the best for grading and they can sometimes have "noise" as evidenced by all the white specks. Some of them are probably marks and such, but I bet most of it is digital noise. Since it is a 1976-S and it appears to be a mint set strike, it should be 40% silver clad as no non-proof non-silver S minted coins were struck.
I am fairly certain this is an MS coin as I cannot make out any rub along the jaw, cheek, and hairline but it does appear to have a bit of a weak strike. It is difficult to determine an accurate grade with the picture quality but I would say it is a mid MS grade 64/65.
