Coinage networks in fifth-century BCE Ionia

This article revisits ‘the problem of Classical Ionia’, the long-persisting idea put forward by John Manuel Cook in 1961 that Ionia experienced regional economic impoverishment in the fifth century BCE. By looking comprehensively at the dataset of coinage available from fifth-century Ionia, this article argues that there is actually significant evidence for regional networking in Classical Ionia, and that various communities, even if not continually emitting new coinages at all points in the fifth century, adopted various strategies for maintaining their economic reach and extending their network of trading partners. Formal network analysis is applied to the coinage dataset, taking the shared weight standards to which communities minted their coins as indicative of participation in common economic networks. The network patterns are tested against two other patterns, specifically the distribution of fifth-century Chian and Samian amphoras, and the pattern of Ionian-coin-containing hoards from within and beyond Ionia. Together, these patterns strengthen the case for a high-level Ionian economic resilience, offering a radically different position to Cook and reaffirming that continuing economic networking was crucial to the activities of fifth-century Ionian states.
