Misaligned hubbing (uncorrected)


Definition: A working die that receives an uncorrected misaligned impression
from a working hub.

Misaligned hubbings occur every so often. If the initial hubbing is misaligned, it is always corrected by a properly centered hubbing. Sometimes the offset hubbing occurs after the properly centered hubbing. In either case, the result is a Class IV doubled die (offset hub doubling).

Uncorrected misaligned hubbings are currently unknown among domestic or world coins. However, Daniel Carr has created some silver rounds that replicate the appearance of an uncorrected misaligned hubbing.

This American Silver Eagle bullion coin was overstruck by a pair of private-issue dies that closely replicate the design of the Walking Liberty half dollar. The host coin’s design has been nearly obliterated. The obverse design was engraved directly into the obverse die in a 15% offset position.

While the result looks like a misaligned die error, there are key differences:

  1. There is no weakness on the reverse opposite the featureless obverse crescent.
  2. The obverse crescent is perfectly flat and smooth. The unstruck crescent of a misaligned strike would bulge toward the viewer, show tumbling marks or, in the case of proofs, display a pocked, burnished surface.
  3. The outer margin of the featureless crescent makes a sharp, right-angle junction with the coin’s edge. A misaligned strike would preserve the planchet’s proto-rim.
  4. The reeding is strong next to the featureless crescent. A misaligned strike would show weakness in the reeding.
