Thank you did you see the 1990 no mint DDR that I posted maybe check it out let me know some about that thank you
The S mint mark is struck in lower mintages in most years therefore commanding a higher premium. So yes.
Picture is blurry. Looks like a slightly misaligned die strike on the obverse. (left rim) No, there is no premium for a regular 70-S. They made almost 700 million 1970-S cents. It's worth .01 cent. It would have to be MS to have more value.
