Tiberius, silver denarius, Lugdunum, c. 18-35 AD, Livia seated left, as Pax. 3.55 g.
It is traditional to identify this issue with the coin held by Christ in Mark 12, because Tiberius was the reigning Caesar, and all other denarii of his reign are far rarer.
VF, toned, minor surface roughness, bankers' marks.
