Just to satisfy my curiosity, I decided to create a tight overlay for the whole date to see how the RPD was positioned. By including the last 9/9 in the overlay, the RPD position is better understood. In fact, there is only one position that accounts for the main markers (dark arrows). The secondary marker (white arrow) matches too.
Compare this shot to the one above–notice the less noise and sharper details? This was accomplished using more diffusion. I also employed a Photoshop technique where you swap the green channel in RGB color mode for the lightness channel in LAB color. Since much of the specular noise on a bronze coin is in the red channel, using the green channel for brightness cuts out much of this noise, resulting in a cleaner, sharper picture.
