ANCIENT ROME, REPUBLIC Anonymous Bronze Quadrans, 190-170 B.C. Head of Herakles / Prow of Galley, ( Bull above prow ) Diameter AE20mm., 6.55gm I am looking for some more information on it because, despite my searches, I cannot 'tie it down'. I know that the three dots represent a 'value' but what is that? Any help is appreciated. Thank-you.
