Roman Imperial Coins are coins that were minted from the initiation of Augustus as emperor (formally Octavian) in 27BC until the reforms of Anastasius (the first Byzantine Emperor) in 498AD. These coins are always in Latin and almost always bare a portrait of the current Emperor (sometimes posthumously) or an Empress or Caesar on the obverse. Reverse type varieties are far too numerous to name here, but include Roman deities, monuments, various scenes etc... Most earlier Roman Imperial coins were struck at the Mint of Rome, with later coins being minted all over the empire and usually bare a mintmark or other symbol noting where it came from. Denominations were usually not marked in words- but are obvious when looking at the size and weight of the coin, as well as the imagery sometimes (Radiate busts of Antoninanii for example).
