Domitian (Titus Flavius Caesar Domitianus Augustus) was the son of Vespasian and the brother of Titus, both of whom were emperors of Rome before Domitian took power in AD 81 upon Titus’ death from illness. Ruling for fifteen years, Domitian had several coins issued and it is relatively easy to find at least a few interesting authentic Domitian coins for sale at any one time.
In addition to genuine Domitian coins, some buyers may also be interested in latter-day reproductions. Check the current listings. Domitian was murdered in 96, after which Nerva took over as emperor for a short time.
