The obverse of this very rare drachm, circulated but well legible, is an example of the series of Hadrian portraits facing left, of which it was possible to recognize the hand of a single skilled engraver who Staffieri G. M. has called "The master of the nude head of Hadrian" (Cf. XV International Numismatic Congress Taormina 2015 - Proceedings - Volume II, pp. 787-788; Roma-Messina, 2017). On reverse, the winged Sphinxs with kalathos and wheel is one of the images of Nemesis, the divinity that presides over destiny and distributive justice.
