Egypt, Alexandria. Philippus I, 244-249. Tetradrachm (Virtually Billon but Silver, 23.39 mm, 13.89 g). Dated RY 2 = AD 244/5. A K M IOY ФIΛIΠΠOC ЄYCЄB Laureate and cuirassed bust right; gorgoneion on cuirass. Rev. Serapis standing, wearing Kalathos, head turned right, is holding a sceptre in his left hand; L B (date) across field. Geissen 2713. Dattari-Savio 4997. Emmett 3506. Really minted in full silver. Very rare as such. Extremely Fine. Ex Victor England (CNG), purchased in 1993. Exceptional tetradrachm struck by Philip I in high-quality silver—an absolute rarity during an economically troubled period when such coins were virtually devoid of it. The flan is also notably thick, comparable to a piedfort. On the reverse, a solemn full-length figure of Zeus Serapis is shown, draped in a mantle, holding a sceptre and wearing a kalathos.
