New to this hobby. What's whizzed? What would drop mean or what do they look like.
Thank you
It is either original mint luster or it has been dipped - pretty sure it was NOT whizzed.

I don't figure anyone's going to dip a 1958-S. I agree, it's mint luster.
I know you meant "D", not "S"; as there were no "S" mintmarks between '56 - '64......and no mintmarks at all between '65 - '67.
