First thing to look for on DDD is the die flow lines on the fields? If you see some, remember the die is aging. When you see the devices are reduced in width or height, remember, die could have been polished. (Or a weaker strike happened) When you see distortion on the devices towards the rim direction. That is DDD. When you see a pushed direction on devices in the same direction it is Machine Doubling. ( Machine Doubling can happen also in several directions also. the machine determines what it can do and does not follow specific rules) Can several things happen on the same strike? Your coin shows it can. But no premium for this. Knowing what can happen is where wisdom starts.
