The quincunx was an Ancient Roman bronze coin produced during the Roman Republic. The coin was valued at five-twelfths of an as (5 unciae) and was only produced during the Second Punic War (218 to 204 BC). It was not part of the standard Roman monetary system and was produced by mints at Luceria (mod. Lucera), Teate (mod. Chieti), Larinum (mod. Larino), and northern Apulia.
