1944 Walker die IGWT compared to 1944 D Walker Die IGWT

1) Does both Philadelphia and Denver use the same dies until the mintmark is added?
2) If so, the 1944 Walker die is dished out due to LDS wear causing distortion of the IGWT and the 1944D Walker die has similar distortion of IGWT but not as bad, thus would this be an EDS of the same die used in both coins? Or is it different dies that are reaching the same worn out die state? You can notice the wear in the field around and above the IGWT. Just curious why two different coins would have such similar die wear in the same places, just for information purposes.

Die erosion is caused by planchet metal movement across the face of the dies. The directions of the movement is determined by the shapes of the dies, which of course is the same on any two dies from the same hub.
That said, I wonder if perhaps your photographs are not precisely sized, causing the apparent differences.

@CaptHenway
They are the same exact settings on the microscope(I remove one ANACS holder after saving and insert the other and save). I understand the causal factors now from the crew in my last post regarding the 1944 Philadelphia, which all stated it was LDS die wear. My question Cap, is their a possibility these two coins 1944 and 1944 D be from the same die or is this an erosion factor that is consistant with these dies. It's just a curiosity about both coins having similar die wear issues in the same area with the 1944 far more worn than the 1944 D which we know the 44 to be an LDS. So maybe the 1944 D being an earlier die state. I absolutely understand it is a no value and nothing to do with die doubling causing the aberrant features. Hope I'm making my questions clear that its just a curiosity about dies used by Philadelphia and Denver being from the same master die therefore the wear caused on one would naturally be caused on another in a similar manner. Sorry, but being uneducated in the dies used by the various mints has escaped my study, which I plan on changing. Is there a specific book available on die preparation and use that you would recommend? I'm too old to change my collection aims, this is just an interesting fact that I have never been interested in until lately.
Thanks again, for your reply.
