The moneyer must be identified with Caius Postumus, accuser of Murena and who was to become legate in 62 BC. (Lucius Licinius Murena was a Roman politician and soldier. He was an officer (legate) in the Third Mithridatic War, a governor (propraetor) of Gallia Transalpina from 64 to 63 BC and a consul in 62 BC. He stood trial because of charges of electoral bribery. Cicero, who defended him, immortalized him in one of his published speeches.). He uses the iconography of Diana Aventina, in reference to the temple erected on the Aventine hill by King Servius Tullius. This temple was built to commemorate the victory of Battle of Lake Regillus about 493 - 499 BC where the Romans triumphed with difficulty over the the Latin League shortly after the establishment of the Roman Republic.
For this type, there are two varieties that are distinguished only by the presence or absence of the king's monogram. The variety without the TA monogram is much rarer. The monogram on the exergue of the reverse may be interpreted as Tatius or Tatianus and refer to the ancient Sabine king.
