Trihemiobol

Metropolis was a minor Thessalian city whose coinage output was limited even by the modest standards of the region's smaller poleis. The trihemiobol — one and a half obols — is an awkward denomination that saw use in Thessaly more than elsewhere in the Greek world, likely reflecting local market customs rather than any broader monetary integration. These decades bracket the period of Macedonian encroachment into Thessaly under Philip II, who effectively reduced the Thessalian League to a client institution by the 340s.

The BCD references here are significant: the BCD Thessaly collection was the definitive private holding of Thessalian bronzes and silvers, and its dispersal at auction in the 2000s established the benchmark attributions still used today.
