ran across this & couldnt make heads or tails of what I was looking at. so I figured id get the best pics I could & just ask. so what am I looking at underneath the top bar of the "7" & to the upper right of the mintmark "D"? the pic off the letter "A" has something running from the bottom left leg up the center of the letter. the other pics I just took because they looked like letters stacked on top of one another, most of the reverse looked like that though.
