Very, very seldom is doubling of the profile at the field actually going to be hub doubling (a doubled die). In fact, I know of no genuine examples.
Pretty much 100% of all profile edge doubling is going to be either reduction lathe bounce doubling or Machine Doubling of one sort or another, and none of it has any premium value.
