This is a great reverse. The obverse is struck somewhat flat on the high points but still a very nice coin for the issue. MSG.
The arch shown here was erected in the Roman forum in honor of Octavian’s victory over Antony and Cleopatra. There must have been a celebration at this location adding reference to the peace established with Parthia – or perhaps the engraved legends on the arch itself were modified at this time. For reasons unknown the arch was later changed to a triple span rather than the single span shown on this type. The foundations of the later arch still exist in the forum. This is one of the few eastern mint types which are dedicated to this event. MSG.
