The coin shown is a large date 1970-S
LMC.
Polite tip for you ghedary ... we do not need multiple upside down and crazy angle photos to help ... one photo each of the obverse and reverse are sufficient ... be sure they are in focus and taken at 90 degrees to the coin ... then rotate them so they are in 'normal' viewing perspective.
Your photo #4 comes closest to this objective ... repeat that next time!
