Note the devices are not enlarged, but reduced in overall size. The area below the damaged device is the size the device should be. During the strike a hop/bounce/die movement damaged that area of the coin reducing the size of the device. Here is a 1957 coin with the same issue, but the image is in 3-D:

This is what happened to this device as well:


Note the reduction on this device? If came from a normal die, but was damaged during the striking process. These are not a doubled die. A doubled die has the doubling on the die and will show the same enlargement on each coin struck with that die:

Hope this helps.
