Siris, a Greek colonial city on the Tarentine Gulf in Lucania, was destroyed by a coalition of neighboring cities — Sybaris, Croton, and Metapontum — around 530 BC, making the precise attribution of coins to this issuer genuinely contested. Some scholars argue production under the Siris name had effectively ceased before this date range begins, with surviving pieces possibly struck by successor populations or during the city's final years before erasure.
