Washington Quarter Struck 70% Off Center on a Clad Layer Uniface Reverse
I bought this coin thinking that it was an off center statehood quarter that split after striking error. The PCGS label was incomplete as in a mechanical label error.
I took detailed photos of the coin, and noticed differences in the un-struck areas of the planchet as you would except to see on a split planchet but, something was off. I studied many examples of other split planchets and concluded that the split happed before striking as the striations of the split metal were on the obverse side and not the expected reverse side. The design in the uniface area happened because of the thinness of the clad layer. The design from the obverse die transferred thru the thin layer as it was struck off center with a second blank planchet underneath creating the uniface ghosting look.
PCGS took the coin back for re-holdering and gave it a detailed label for this uniquely rare multiple error coin.
Here is the PCGS holder with the original incomplete label:
