This is one of the few instances where an early Roman Republic coin can be tied to a specific year because the Sardinian Praetors of 211-209 BC are recorded as Cornelius, Manlius and Aurunculeius and conveniently a series of 3 issues, each of similar style and fabric, commonly overstruck on Sardo-Punic and primarily found on Sardinia, are mint marked with C, MA and AVR. This sextans is from the 'AVR' series, thought to have been struck under Sardinian Praetor of 209 B.C., Caius Aurunculeius Cotta. See here for an example of the related C issue of L Cornelius Lentulus, Sardinian Praetor of 211 B.C..
