There are several different ways that a doubled die can be created. The ones that people are most familiar with are caused by the hub and the die being misaligned between hubbings. In other words the hub is pressed into the die blank, then the partially completed die is annealed to soften it and the hub is pressed into it again. If the die and the hub are not perfectly aligned between the two pressings the die will show a doubled image. The die and hub can be shifted to one side in relationship to each other, or they can be rotated. In the case of a rotation misalignment the point around which they are rotated can either be in the center of the die (a class 1 doubled die) or at any other point but the center (This is a different class but I forget the number)

Other types of hub doubling can be caused by the die becoming distorted during the annealing process so that features aren't in quite the same place as they were during the first pressing, or the die could be pressed by two different hubs, one sharp and new and the other worn and slightly distorted, or the die could be pressed by two different hubs that have different designs. Such as the 1943/2 P nickel. the 1942/1 P and D Mercury dimes, the 1909/8 double eagle etc. there are a couple of other types as well.
