Hemiobol

Kierion was a minor Thessalian polis of the Histiaeotis region, and its coinage output was modest enough that the hemiobol denomination survives today in genuinely small numbers. The BCD collection — assembled by a single specialist over decades with a focus specifically on Thessalian issues — remains the primary reference for attribution, which itself signals how little mainstream numismatic attention this series has historically attracted. The SNG Fitzwilliam variant notation suggests meaningful die differences exist within the type, though a full die study of Kierion's fractional silver has never been published.
