Before striking silver at Rome the Romans had struck silver coins with type of quadriga and ROMA in Campania. Hence it is that Pliny regarded these the quadrigati and bigati as the oldest issue instead of the coins with the Dioscuri (Fig. 54). The biga came next, after it the genuine Roman quadriga.
