For some 200 years, Roman gold coins anchored the Roman monetary system. Bronze and silver coins had a fixed relationship to the gold ones. When both the fineness and the weight standard of the gold coinage were radically reduced in the mid-third century AD, it appears this fixed relationship finally collapsed and a fundamental shift in Roman economy was caused. The fabric of Roman gold coins is, then, a highly important part of Roman economic history. In this proposal we intend to examine the three evidently debased coins of Galba, Otho and Vespasian.
