Missing Clad Layer:
Partial:
Before Strike
Definition: Part of the obverse or reverse clad layer is missing from the planchet. Loss of cladding sometimes occurs before the clad strip is rolled to final coin thickness. In such cases the coin weighs the same as a normal coin. In other cases the cladding is lost after blanking but before the strike. Such coins will weigh less than a normal specimen.
This 1999-P Washington Statehood quarter (Georgia) was struck on a planchet that was missing part of the clad layer on the obverse.
