1960 P Nickel - Need Help.dd, MD, Or VLDS?

I would say Die Deterioration. I am not the expert though.

Die wear and Machine Doubling, but not a doubled die. On the areas you are looking at, are the areas where you see die wear and Machine Doubling. Look at the centers of the devices. Not on the outside edges of the devices.
Here is an example of a proof nickel with a DDR. A lot of images, but note where you see the spread on a nickel DDO-DDR examples:

So many times on the Variety Vista site, New Ones will miss that information on the description. So they match it up their coin to the normal images and think, "I have that die on most of the devices." But the description information is the variety, the other images are normal images with slight hub doubling or use for markers on to match up to determine die state/stage. In order to be that die number all the hub doubling must match up. (there are times when the class 2 doubled dies will loose the spread lines because die wear on the outside edges of the devices. But on other devices in the center areas, it will show the hub doubling as the die wear doesn't affect that area yet.
