Dear cf, i am glad to have this very rare coin in my collection. it's so far the only known Didrachm on hadrian his Egypt currency, the 2e known so far. Reference. RPC III; 5776=Paris 1689; Emmett --; Dattari--; Issue L IE = year 15 Obv. ΑΥΤ ΚΑΙ - ΤΡΑΙ ΑΔΡΙΑ СƐΒ Laureate head of Hadrian r., drapery on l. shoulder Rev. L ΙΕ Draped bust of Sarapis, wearing kalathos and laurel wreath, right 4.95 gr 16 mm Note. RPC III states on Paris coin Unique. Note that the obv. bust is the same as that used on small AE denominations; however the coin cannot be a cast forgery in silver since the reverse design is not used on small denominations. In addition, the fabric of the coin is different from that normal for AE (e.g. the edge is not bevelled). Show your surprise Coins
I found this quinarius by Hadrian _ RIC 688. And also Sarapis on reverse of another coin which was struck outside Alexandria under Gallienus.
