That type of doubling is called
DDD (Die-Deterioration-Doubling) The die is aging and the devices are normal, but the area you are looking at is the field altering from die wear. We see this more often on the obverse dies, but it can show on both sides of the coins struck with these dies.
Why are these not doubled dies, if the dies are creating these? A doubled die is cause with a hubbing issue. Alighments can be incorrect. Hubs can can be worn, warped or damaged and the make the die incorrectly. But on doubled dies, the coins struck with be doubled from coin #1. On the
DDD, the die was normal when created, but as the die aged, the devices started doing what happens on every die, wear. The wear is always in the direction of the closest rim. On the single squeeze dies it is the fields that show the
DDD:
On the older style dies I refer to as 'multi hubbed dies' the devices actually move to the rims:
To see this with a different set of images, it is a progressive wear process:
So these are not a doubled die. It is an aging die, reaching retirement soon. Hope this helps.
