Æ20 - Domitian L Ι

Regnal year 10 of Domitian's reign, which is what the "L Ι" denotes — the Greek letter iota marking the tenth year of his tenure as emperor. Alexandria's civic mint operated under close imperial supervision, and Egyptian bronze issues of this period were strictly fiduciary, their value entirely dependent on Roman administrative control of the province. Egypt remained a closed monetary system: coins minted there did not circulate freely outside its borders, and foreign coinage was officially exchanged upon entry.
