This paper investigates the everyday use of coins at the Roman Red Sea ports of Berenike and Myos Hormos, challenging their conventional interpretation as mere indicators of trade prosperity. Adopting a contextualized approach, the paper analyzes coin finds alongside non-numismatic evidence – including ceramics, botanical and zoological remains, and epigraphic records – to uncover their role in daily economic activities. The study demonstrates how coins functioned across diverse settings such as marketplaces, industrial zones, religious sites, and residential areas, highlighting their integration into the economic, social, and cultural fabric of the ports. Beyond serving as a medium of exchange, coins played crucial roles in taxation, service payments, and religious offerings. By reconstructing the transactional dynamics of the ancient ports, the paper provides new insights into the interactions between residents and visitors, enriching our understanding of daily life in these vibrant hubs through a holistic archaeological perspective.
