I am going to show two features on two coins. The non-burnished spot west of the eagle's beak does get slowly bigger over many coins as the die wears. The "scratch", for lack of a better word, that goes from the eagle's west wing through the the upper west star is just one other feature that seems to be the same in many of these coins. I am not sure what causes it but, it is only visible when the light comes from the side.

I have more photos at higher magnification.
I welcome any thoughts or ideas.
