Hemiobol

Pantikapaion — modern Kerch, on the eastern tip of Crimea — was among the earliest Greek colonies in the Cimmerian Bosporus, and its silver fractions from this period represent some of the first coinage struck in the entire northern Black Sea region. The city's economy ran heavily on grain export to Athens, a trade relationship significant enough that Athens granted Bosporan merchants preferential tariff treatment by the fourth century.

At 0.45g, this hemiobol circulated as genuine small change in a colonial market where fractional silver was the practical currency of daily transactions.
