This looks like toning, not a missing clad error.
A coin with both clad layers is almost impossibly rare. Only a few have been certified. It would also be about 2 grams underweight unless the planchet was punched from a solid copper sheet rolled to the correct thickness of 1.75mm.
Missing clad usually causes some weakness of detail in the strike. This is caused by the too thin planchet being struck with the correct die gap set for a normal full thickness planchet.
