1 Quincunx

Ariminum (modern Rimini) was established as a Latin colony in 268 BC — the same year this series is believed to begin — making it one of the earliest Roman colonial mints on the Adriatic coast. The colony sat astride the Via Flaminia and served as Rome's principal staging point for campaigns into the Po Valley and against the Gauls. The quincunx denomination, representing five-twelfths of the as, appears only sporadically in the aes grave series and is among the rarest fractional divisions produced.

Haeberlin's die study places Ariminum output as distinctly local in execution, with casting quality differing measurably from contemporary Roman and Etruscan production.
