In view of the uncertain reading on the obverse, we cannot be sure of the attribution. F. Kovacs suggests (in litt.) Buthrotum. In favour of that attribution are: the two fishes (RPC 1416-1417: Neronian), and the dolphin (RPC 1392: Augustan) and the very unusual occurrence of the word PVB (RPC 1395-1397 have PVBL: Claudian; this seems to be the only occurrence of the word, whatever its exact significance, in RPC I), while D D is too general to help. A date in the Triumviral or Augustan period seems likely.
