Octobol - Xenocrates

Chalkis was one of the few Euboian cities to maintain an active mint into the second century BC, a period when most Greek civic coinages were being squeezed out by the expanding reach of Macedonian and later Roman monetary influence. The octobol denomination — eight obols, or two-thirds of a drachm — is an unusual unit that appears sporadically in Euboian issues and reflects a local accounting tradition rather than any pan-Hellenic standard. The magistrate name Xenocrates places this piece within a specific administrative sequence documented by Picard's die study, narrowing its production window within the broader 180–146 BC range.
