Æ34 - Antoninus Pius L ΔΕΚΑΤΟΥ

The L ΔΕΚΑΤΟΥ inscription places this coin in regnal year ten of Antoninus Pius — 146/147 AD — a period when Alexandria's mint was producing some of its most ambitious bronze issues under the prefecture of Egypt. Alexandrian bronzes of this reign are notorious for irregular fabric and inconsistent centration, a product of working conditions at a mint serving a province treated as the emperor's personal estate rather than a senatorial territory. Egypt's unique administrative status meant its coinage remained deliberately incompatible with the rest of the Roman monetary system, non-exportable by law.
