Just Machine Doubling as mentioned. The coin was damaged after the strike. Note the overall size of the devices are normal and the top areas your looking at have been altered by machine movement with the dies. You won't find Machine Doubling listings as it is different from strike to strike:
Note on these examples I found in rolls of the same run. Note the marker on the lower left area is seen on each coin. The Machine Doubling was different on each strike. All caused by the same dies, the same machine and the movement after the strike by the machine.
You will find doubled dies listed as they are the same (excluding die wear and die events) from coin one, till retirement. They look different because of the different dies created with hub/die errors. They are called a doubled die because the doubling is on the die. But that is the difference? On doubled dies they are striking what is on the die. On Machine Doubling the machine causes the alteration on the devices. Machine Doubling is very common to find. A doubled die is harder to find and are more desirable.
Note how the affected areas are flat/shelf like/reduced from the normal size of the devices? These images areas are all from the same striking event, from the same dies, on the same coin.
Doubled dies show enlarged devices:
If you have two different dies that have a doubled die on each one, Will they be different?
Yes, that is why they have different numbers. Because they were identified as not coming from the same die pair.
Next question: Can Machine Doubling happen on a doubled die? Yes.
(Note yellow arrows for machine doubled areas)
So why can Machine Doubling happen on a doubled die? The same way it can happen to a normal die. It is caused by the same die movement during the strike. These are still doubled dies, but less desirable to a variety die collector. Hope this helps?
