This anomaly is very common on late 80's and early 90's zincolns where there are split plating issues and Die Deterioration Doubling. It is not an actual doubled die.
It is an issue with Die Deterioration. The coin on the date is showing wear towards the rim. There reverse maybe the same thing, but not seeing the tops of the devices I can't say for sure. If the USA is showing the same thing on the tops of the devices, then it is Die Deterioration. If not, then I would need to see more of the coin to see what is going on.
The "ghosting" effect was explained to me as a result of heat accumulated on the dies due to the higher speed of the presses and thin copper plate on zinc planchets. This seemed to show up early 90's when new press processes were introduced. IMHO an explanation as any
