Silver 1 As Octopus series: six tentacles

Populonia was the only Etruscan city to strike its own coinage directly in metal smelted from local ore — a consequence of its position at Piombino on the Tyrrhenian coast, controlling some of the richest iron deposits in the ancient Mediterranean. The silver for issues like this one almost certainly derived from trade revenues generated by that iron trade rather than from local silver mines. The octopus type, used across multiple denominations in the Populonian series, likely carried commercial or maritime associations tied to the city's active port economy rather than any civic or religious program in the Greek sense.

The six-tentacle variety is distinguished from the more common eight-tentacle dies in the Vecchi classification — a detail that matters for attribution and relative rarity within the series.
