Only for Valentinian III.
RIC 2140-2141 "AE3/4" for Valentinian III, from Rome, both "S",
plate 53 (one photo), p. 379. Note that this photo, with "XV" has a
photo
where the "V" might almost be an "X" and the type then looks like type
72 "VOT / XX".
"[This type] can scarcely be later than about 440." RIC p. 174, which
places it in 440-455.
