The reaction uses calcium hydroxide and elemental sulfur to oxidize away the pennys copper plating but not the underlying zinc. Just check there is no soft soldering or braze anywhere as ammonia will also eat tin zinc and to some extent attack lead. Heat the solution to the temperatures between 350 and 400 degrees Celsius and immerse the gold plated copper into it until the gold plating has been removed completely.
