Domitian was the last emperor of the Flavian dynasty and minted many Alexandrian bronzes during his 15-year reign, but only occasionally (in years 4, 6 and 8) minted silver tetradrachms like ours of the year 6 (86-87), of absolute rarity and valuable style, coming from the famous Giovanni Dattari collection. It is also the only Alexandrian coin with the legend on the reverse that expressly indicates the Nile as the deity engraved on the roundel with all the attributes: crown of lotus flowers, cornucopia, ears of wheat, other lotus flowers emerging from the waters of the river and the hippopotamus.
