Watch List notes:

Mysia, Syria or Cyprus, Ephesus, Pergamum, Antioch or Paphos(?). Augustus. 27 B.C.-A.D. 14 AE 27 dupondius (26.5 mm, 13.01 g, 1 h). struck ca. 25 B.C. AVGVSTVS, name clockwise behind bare head of Augustus right, all within dotted border / large CA within rostral wreath (ships' beaks and laurel-branches) between dotted inner and outer borders; between wreath ties, a large pellet. RPC 2234; BMC 721; Howgego 2b. VF / Good VF, toned brass highlights on devices and dark green patina in fields. 

There is no universal agreement as to which of several important cities coins of this nature belong. Ephesus, Pergamum, Antioch and Cyprus (among others) have been plausibly proposed but none is fully supported. The exact meaning of "CA" is also at issue with many interpretations offered. Caesar Augustus and Commune Asiae are among the more plausible interpretations.
