Dupondius




The dupondius (Latin two-pounder) was a brass coin used during the Roman Empire and Roman Republic valued at 2 aes (1/2 of a sestertius or 1/8 of a denarius).
The dupondius was introduced during the Roman Republic as a large bronze cast coin, although even at introduction it weighed less than 2 pounds. The initial coins featured the bust of Roma on the obverse and a six-spoked wheel on the reverse.
