Year 16 of Antoninus Pius corresponds to a period of studied administrative calm in Egypt — no revolt, no flood crisis on record, no rupture in the grain supply that fed Rome. Alexandria's mint ran continuously through his reign, and the sheer volume of Æ coinage produced under Pius makes individual die varieties within the series genuinely difficult to attribute without reference to the Dattari-Savio corpus, of which IV.4#1436 is a product of decades of reclassification work completed well after Dattari's original 1901 publication.
