Trichalkon

Metropolis was a minor Thessalian polis whose coinage output was limited enough that the entire known series fits within a single BCD auction catalog sequence. The city sat in the Thessaliotis region and operated largely under the political shadow of larger neighbors — first the Thessalian League, then Macedonian hegemony following Philip II's reorganization of the region after 352 BC. That political subordination likely explains the modest scale of local bronze production across the type's long attributed span.

BCD Thessaly II remains the principal reference for this series, drawing from the collection assembled over decades by a single anonymous European collector whose holdings defined modern scholarship on Thessalian bronzes.
