Here is a first remarkable tetradrachm belonging to a peculiar Alexandrian series of the so-called "Roman style", closely related to the current issues of the Latin area of the empire: this suggesting the presence in the Alexandria mint of good engravers coming directly from Rome. In the series are coins minted exclusively in years 4 (224-225 AD), 5 (225-226 AD) and 7 (227-228 AD) of Severus Alexander's reign and are distinguished from ordinary issues by the particular classical idealistic refinement of the images and by the slightly larger size.
