Quadrans Aburii: Marcus Aburius Marci Filius Geminus, M•ABVRIMF GEM ROMA

Marcus Aburius Geminus served as moneyer around 132 BC, a period when the Roman Republic was fracturing under the pressure of the Gracchan land reforms — Tiberius Gracchus had been murdered the previous year and the political violence his death unleashed was still reverberating through the Senate. The quadrans denomination by this point was in sharp decline as a practical currency, its purchasing power eroded by decades of weight reduction under the uncial and then sextantal standards.

Crawford places this issue within a sequence where the quadrans was approaching obsolescence in everyday transactions, rarely struck in quantity.
