Another "Dattarian" hemidrachm showing on obverse radiate bust of Antoninus Pius, which RPC IV. 4 has cited and illustrated, is one of only two known specimens, what Staffieri ranks sub 26 a. It is not by chance that this coin, like the previous No. 404 in the collection, was minted in the symptomatic Sothic year 138-139 AD corresponding to the second Egyptian year of the reign of Antoninus Pius. (Cf. comment to No. 398 in the collection).
