Denarius - Nero PONTIF MAX TR P VI P P

Nero's sixth tribunician year — the window that dates this issue to 59–60 AD — places it precisely in the months surrounding his murder of Agrippina the Minor, his own mother, in March of 59. The imperial mint under Nero was already shifting authority away from the Senate, and the coinage of this period reflects a deliberate consolidation of priestly and tribunician titles as political instruments rather than ceremonial ones.

RIC I 18 is well-documented as part of a larger Neronian series struck before the significant debasement he initiated in 64 AD, when silver fineness dropped sharply and flan weight was reduced. This piece predates that reform by several years.
