If I were a little more computer savey , and both your MM picture and the one on the V16B page were not quite so zoomed in . I would make both of the pictures the same size as best I could and overlay them . I would try and find the most common reference points on both pictures, hoping to compensate for both die wear and circulation wear . I would even leave the way both of the red-lines have been draw on , so we could visualize any differences or similarities .
About a year ago we got on the subject of MM placement being subjective on this board . We have all seen the guides in the bigbook describing the ins and outs of tilt , left and Right , up and down . I have heard a lot of opinions about how to interpret the way the listings were written , but I also learned a great deal about just how different some folks found things like center line and what they used for reference points .
I am not saying you are right or wrong at all .
I am saying I am not absolutely sure if the MM on your specimen is in the same spot or not .
I did not really look for confirming die markers on both reverses pictured to explore the possibility of a different reverse on your specimen . So how does one really make the best educated guess on this stuff???? , Beats me
