Sextus Quinctilius - Monetalis of Res Publica Romana from 189 BC to 180 BC
Sextus Quinctilius was one of the moneyers for the year 189-180 BC. He is not otherwise known.

Quinctilia, also written Quintilia, was a patrician family at Rome, dating from the earliest period of Roman history, and continuing well into imperial times. Despite its great antiquity, the gens never attained much historical importance. The only member who obtained the consulship under the Republic was Sextus Quinctilius Varus in 453 BC. The gens produced numerous praetors and other magistrates, but did not obtain the consulship again for over four hundred years.

The nomen Quinctilius is a patronymic surname, based on the praenomen Quintus, meaning "fifth". Quinctilius is the correct orthography, but Quintilius is also quite common. The gens Quinctia is derived from the same praenomen. It was not unusual for multiple nomina to be derived from a common source; the Sabine name Pompo is the Oscan equivalent of Quintus, and gave rise to the gentes Pompilia and Pomponia.
