Watch List notes:

PONTUS, Neocaesarea. Severus Alexander. AD 222-235. Æ (28mm, 12.69 g, 12h). Dated CY 163 (AD 226/7). Laureate, draped, and cuirassed bust right / Two-storied portico (nymphaeum?) with central arch in which stands Tyche holding [rudder] and cornucopia; [ЄT PΞΓ] (date) in exergue. Çizmeli 244 var. (D1/R– [unlisted rev. die]); Price & Trell fig. 71 (for rev.). Fine, earthen green surfaces. Rare.

Price and Trell (pp. 43-4) include this type with other coins depicting nymphaea, but caution that "...the building at Neocaesarea resembles a gate more than a fountain and certainly does not have the spouts at the base to indicate the nature of the monument."
