It looks like very slight machine damage that you are looking at. You are seeing to much in your images. When you do find a doubled die, it will leap right out at you. At first we miss a lot and pretty soon we are seeing too much. So if there was a doubled die, you would see if for sure. It is good you have your eye trained, but when the camera no longer sees what you are seeing in your scope, then it is too minor to interesting at that point. We have all been there. But keep looking. It will jump out at you and you will have no question when you find a doubled die.
