This is the strongest of the 1905 and 1906 doubled dies, because of the full seperation of the veins, the doubling here is easily visible on just about any grade. You should make a habit of checking every 05 and 06 reverse. This particular double die comes married with an obverse that has a repunched date, the 1905 RPD-014.
Paired with RPD-014. Die scratch through TE of UNITED.
Class II, Distorted Hub Doubling.
