Hard to tell from this view. The inverted pics were better.

On my previous post about a machine doubling on a 1983 cent, Rick asked me to post non inverted pics. Here they are. 1 shows the inverted version.
To be honest, I do not remember the thread, but the one that says dd.jpg is an example of Mechanical doubling ( MD or MDD [damage]. Notice the main portion of each letter shown is much more narrow than the center portion. A hubbed double die, will increase the thickness in the doubled area because the first hubbing will be overlapped by the second so 1+ a fraction. In MD, it is narrowed and the flattened portion subtracts from the width, 1- a fraction. After 1995 or thereabout with the advent of single squeeze hubbing, which is just once, and doubling is mechanical (MD) to classicists and possibly called a DD by modernists. IMO MD . Jim
