The denarius was the standard Roman silver coin from its introduction in the Second Punic War c. 211 BC to the reign of Gordian III, when it was gradually replaced by the antoninianus. It continued to be minted in very small quantities, likely for ceremonial purposes, until and through the Tetrarchy (293–313).
Denarius of Octavian and Mark Antony, struck at Ephesus in 41 BC. The coin commemorated the two men's defeat of Brutus and Cassius a year earlier as well as celebrating the new Second Triumvirate.
Flavia Domitilla, wife of Vespasian and mother of Titus and Domitian
Quintus Antonius Balbus (c. 83–82 BC)
The dupondius was a brass coin used during the Roman Republic and Roman Empire valued at 2 asses.
Sestertius of Hadrian, dupondius of Antoninus Pius, and as of Marcus Aurelius
Dupondius of Vespasian (69–79), struck at Lyon in about 72–73. This coin seems to have escaped the serious corrosion typically observed in ancient coins and thus retains nearly its original appearance and colour, showing why the Romans sometimes also called this alloy aurichalcum, from aurum for gold in Latin+"-chalcum" as in the most widely used orichalcum. The coin measures about 29mm in diameter.
