The reverse image depicts the Altar of Pax (peace) found on coins of Tiberius, Nero and perhaps others.
Some history:The Ara Pacis
Augustae (Latin, "Altar of Augustan Peace"; commonly shortened to Ara Pacis) is an
altar in
Rome dedicated to Pax, the Roman goddess of Peace. The monument was commissioned by the Roman Senate on July 4, 13 B.C. to
honor the return of
Augustus to
Rome after three years in
Hispania and Gaul, and consecrated on January 30, 9 B.C. Originally located on the northern outskirts of
Rome, a Roman mile from the boundary of the pomerium on the
west side of the Via
Flaminia, it stood in the northeastern corner of the Campus
Martius, the former flood plain of the
Tiber River and gradually became buried under 4 metres (13 ft) of silt deposits. It was reassembled in its current location, now the Museum of the Ara Pacis, in 1938.
