S.D. Codified Laws § 32-5-170

If the emblem specialty plates are requested at the time of initial application for title and registration of the vehicle, no additional fees are charged for the plates above the costs involved in registering the motor vehicle. If the emblem specialty plates are requested later or if the motor vehicle has current South Dakota plates, the owner shall surrender the current plates and pay a ten dollar fee for the emblem specialty plates. All fees collected under this section shall be placed in the license plate revolving fund.
