Sorry but from the images provided, it appears to be Machine Doubling. Note the mark on the "N" is actually reduce the side of the device and not enlarging it. The tops of the motto could be die flow or more Machine Doubling. If it is flat shelf like, it is Machine Doubling. If there is a pattern of die flow in this area it is die wear. Either way, not a collectable. I would hang onto it for now until I see some better close ups of that area. If this was a proof coin, I would think it is flat field doubling. You see that on proof coins as the two strikes on cents don't exactly match up creating a strong strike double that you can see what appears as movement on the surface of the coin.
Here is an example: (Note the arrows in red on this image)

See where the devices were pushed from the previous strike. The die was a doubled die but also has flat field doubling. I used to think it was a tripled die, but it is not.
