As Coin, c. 187-155 B.C.E, Unknown Minter, copper, 1.25 inches diameter, Drs. Arthur and Roswitha Haas, 2015.7.4.
A Roman Republic copper As coin by an unknown minter. The laureate, double head of Janus is featured on the obverse with no inscription. While it is conventionally thought that the month of January is named for Janus, the god of beginnings and transitions, and also of gates, doors, doorways, passages and endings, but it is actually named for Juno, who was, among other things, the protector and special counselor of the Roman state.
