Trichalkon

Metropolis was a minor Thessalian polis whose coinage output was modest enough that the city barely registers in ancient literary sources. What survives does so almost entirely through archaeological recovery rather than continuous collection history. The BCD Thessaly II reference places this piece within a sequence assembled by the late collector known only by his initials, whose Thessalian holdings represented the most systematic private accumulation of the regional series in the twentieth century.

HGC 4#258 confirms the type's rarity rating as scarce.
