Die wear is also needed to be figured in. Note the die flow direction on your coin? Those area are in that same direction. Die flow is the cause. I can can enhance something that wasn't the were the die was fresh. What can cause I to appear before a device you may ask? An older die scratch can start a die flow line. Die scratches flattened quickly on the open fields. But near devices they remain longer. In side on a device a lot longer.
