Watch List notes:

Severus Alexander, 222-235. (Bronze, 32 mm, 21.45 g, 6 h). Anazarbus in Cilicia. AYT KA M AYP CEOY AΛΕΞΑΝΔΡΟC Laureate, draped and cuirassed bust of Severus Alexander to right. Rev. ANAZAPB/OY A section of arched aqueduct supported by eight columns and with three towers; statues of winged Nikai along the top of the stepped water conduit. Cf. Ziegler 546 = Price & Trell 46, fig. 81, otherwise unpublished. For an additional specimen from the same dies, cf. CNG e318, 2014, 432. The second and finest known example. Green patina, and with a sharp portrait and an exciting architectural reverse. Minor porosity, otherwise, extremely fine.

The reverse of this coin shows the aqueduct at Anazarbus, the ruins of which still stand today. Price & Trell suggest that the pyramidal towers seen along the top may be sluice gates.
