Silver 20 Asses Gorgoneion series II: trident with crescent

Populonia, the only Etruscan city known to have struck coins directly from locally smelted ore, drew its silver from the iron-rich deposits of Elba and the surrounding coastal mines — an arrangement that gave its mint an unusual degree of raw material independence during a period when most Italian minting authorities relied on trade or plunder for bullion. The city's output declined sharply after Roman forces sacked it around 282 BC, which almost certainly compresses the actual active striking window for this series considerably.

The trident with crescent combination places this among the later denominations of the Gorgoneion sequence, a classification refined substantially by Italo Vecchi's 1992 corpus.
