| 裏面の説明 | A multi-arched bridge spanning a river, depicted in profile with eight supporting piers and a flat roadway above; the structure is generally identified as the Bridge of Apollodorus over the Danube, constructed during Trajan's Dacian campaigns. A small boat or vessel is visible beneath the bridge in the lower right portion of the field. The reverse legend S P Q R OPTIMO PRINCIPI appears in the upper field, honoring Trajan as the Senate and People of Rome's finest ruler. The senatorial authorization mark SC (Senatus Consulto) is placed in the lower exergue area. The overall design closely replicates the sestertius type attributed to the Roman Imperial mint at Rome, struck circa 103–111 AD. |

Trajan's Danube bridge, completed around 105 AD under the engineer Apollodorus of Damascus, was the longest arch bridge the ancient world would see for over a thousand years — spanning roughly 1,135 meters on 20 stone piers. The original sestertius commemorating it is among the most historically loaded bronze issues of the Principate, struck to mark the infrastructure that made the second Dacian campaign logistically possible.
This is a modern replica. The brass composition confirms it immediately; ancient sestertii were struck in orichalcum, a zinc-rich brass alloy whose precise formulation was lost well before the third century.
