A lamination is a peeling away of the solid planchets. This occurs on silver,copper and copper-nickel coins. I've not seen a quarter that is sandwiched suffer from lamination. On the composition coins they maybe partially missing or whole coin missing the silver outside part.


The cladding is either missing or peeled off after the strike. Unlike laminations that may happen before/during/after the strike.
The OP's coin looks like it was suffering from acid placed on the surface.
