The quartuncia was the smallest denomination issued during the time of the Roman Republic. These bronze coins had a value of 1/4 uncia and were minted in low numbers only between 222 and 200 BC.
Quartunciae showed the head of Bellona, the goddess of war. The reverse bore the typical motif for Roman bronze coins, a prora, a ship's prow. In Roman language the association of ships and coins lasted for a long time: in the 4th century AD, it was still a custom in Rome to ask 'capita aut navia?' (heads or ships?) when tossing a coin.
