Tetras

Kefra was a small Sikeliot mint in ancient Sicily, operating in the shadow of larger neighbors like Syracuse and Akragas. The tetras — worth three onkiai, one-quarter of a litra — was a workhorse denomination in the Sicilian bronze system, and issues from minor mints like Kefra are typically short-lived, tied directly to local civic ambitions that rarely outlasted a generation of political stability.

CNS 7 places this type within the Corpus Nummorum Siculorum, the standard reference for Sicilian coinage, though Kefra's output remains poorly documented compared to the island's major centers.
