Trihemiobol

Caria in the mid-fifth century was a fractured region of semi-autonomous dynasts and cities operating under loose Achaemenid suzerainty, which makes firm attribution of minor silver fractions like this one genuinely difficult. The trihemiobol denomination — one and a half obols — served small-transaction commerce in a world where a single obol could buy a day's basic provisions.

The SNG von Aulock reference places it within a recognized but poorly documented group; von Aulock's collection itself was assembled largely from trade sources with incomplete provenance, which compounds the attribution problem.
