Gnecchi F. Coin Types of Imperial Rome

London: Spink & Son, 1908. — 101 p.The Imperial Roman Coinage, during the four centuries from the beginning of the Empire until the time of Romulus Augustus, gives us, in uninterrupted succession, a series of little less than two hundred rulers.In the obverse types of the coins, we have a more extensive series of portraits than is generally known; in the reverse types a series so numerous and varied that it may almost be called infinite.While, however, the first has been repeatedly described and illustrated, the second, although numerous studies refer to it, has never been completely described.
Such will be the scope of this work in which I propose to give in sigheth form a general view of the coin types of the Empire.
