I have a magnetic 2011 24k gold plated Kennedy half dollar. Are gold plated half dollars supposed to be magnetic for that year ?? Because I have 1974 24k gold plated and it's not magnetic, so can this be some sort of error or worth anything ??
It's apparently fairly common to put on a layer of nickel plating before applying the gold -- gives more consistent and durable results, as I understand it. And pure nickel is strongly magnetic.
Might be something else besides gold they used for the plating. Even though.. it's not worth more than .50 Cents
