The close-ups do not reveal anything at the monument base, however, the full obverse shot seems to show something which leads me to think it is the worthless super weak variety. Please confirm or comment so I may move on. Sorry it's a 1969 D Thanks!
Going thru my 1969 D's and found another that looks even more definitive... 2bd full obverse shot shows 2 small dots.
Look up floating roof. Your coin is not quite, but, if you understand the floating roof attribute it may help you understand the stage your cent is in.
Its very interesting that the four "dots" match with the FG but close inspection that FG disappears. The very first photo let's our mind "fill in" the details. Sorry for the false alarm!
