Doubled Dies:

Class IV: Offset Hub Doubling

Offset Hub Doubling

This coin exhibits hub doubling that occurred as a result of a hub or die being offset in any direction from the center of the design. The doubling is spread across the entire design in the same direction. The strength of the hubbing determines how far out from the center the doubling can be seen. The 1909 DDO-001 is a good example of a class IV doubled die where the initial hubbing was not very deep. Thus the doubling is primarily visible on the central design elements (RTY of LIBERTY and 190 of date). Many times the offset is also combined with a tilt which results in a hybrid (Class IV+VIII) and shows the doubling only on one side of the design.

Notice how the doubling flows in the same direction from Right to Left.
