Doubled dies are created during the die making process. The hub is press into die stock to make a die. If the alignment/rotation/different hub is incorrect it makes a doubled image on the die. Thus a coin struck with that die will be a doubled die. The doubling is on the die. So the devices will be different than a normal dies coin. Some wider, taller, showing notching, warp on the hub will make the die to look different in just some areas of the die. Thus there are 9 different classes of doubled dies.

These show a rotation of the hubbing. (probably the most desirable of the doubled dies)





These are the strongest and easiest to find. Most of the 1972 doubled dies fall into this class and many others.
