Valliant, Joannem. Numismata Imperatorum Romanorum Praestantiora, Vols. I-III (Rome: 1743), tall quarto (11 in.), three-quarter leather over marbled boards, spines with raised bands and gilt, title pages in black and red, each with a different classically-inspired allegorical engraving; all text is in Latin. The first volume presents a catalogue of coins and medals produced by the dictator Julius Caesar and thereafter by the emperors from Augustus through Constantine the Great; the second volume describes roughly 300 years of Roman gold and silver coins from Julius Caesar to the 3rd century A.D.; the third volume covers medallions struck under the later Roman emperors and beyond, to include several Byzantine rulers.

Each title page is impressed with the blind-stamp of Cheryl Anne Gaver, one of the principals of the 20th century numismatic firm Collectors Research of Montreal, Canada.

Internally clean with tight binding for the text; the listings are sometimes identified as marginalia denoting AV (gold) and AR (silver); the boards are well-worn throughout, the top ones being detached from the spine at the hinge. Overall a clean and useful set that does honor to the study of Roman numismatics.
