If one is raised, and one is incuse, then it was transferred off another coin edge. These devices should all be incuse on these coins as they were added post strike to the coins. If it were a doubled affect, then all the devices would be showing. (Not just one, on one area) On the Proof dollars, they are added during the strike with three dies in place. (Collar has the devices on it)

On Business strikes they are added later.
