One of the three die progressions I just posted, shows the moment the 7 becomes a wide upper 7. The seven becomes doubled on the bottom that is still showing the modification actions. We can see two upper right corners and a separation doubling. Moving north also is seen in doubling along the southmost part of the upper 7. This double wide seven then stayed that way through the life of that year.... and is still visible on all 1977 Lincoln Cents and 1977D Lincoln Cents.
So, if we take up a collection and buy you a telescope to replace your microscope, will you go spam the astrology forums instead? Because what you're doing (taking random images and working with all your might to find meaning in them) seems exactly like astrology to me...
