You rock GSP! That was so helpful!
There are several die marks on the images that are clearly above the surface die issues (chips, scratches, and breaks) that are not progressions of each other and can't be from the same working die set.
These clearly distinct die markers on the 5 PCGS reference coins are in totally different locations and have totally different shapes.
Since the die marks come from the working die, do you think the doubling occurred upstream of the working dies? Perhaps on the hub that was used to make multiple working dies, or even farther upstream?
In case it is helpful, I limited the images to one section of the reference coins so comparisons could be readily made among the 5 examples. There are many additional distinct die marks besides these.
