As - Nero PONTIF MAX TR P IMP P P

Nero's aes coinage underwent a deliberate reduction in module and weight beginning around 64 AD, likely connected to the financial pressures following the Great Fire of Rome and the enormous expenditure on the Domus Aurea. This particular issue, carrying the PONTIF MAX TR P IMP P P titulature without a tribunician power numeral, belongs to the earlier part of the 62–68 sequence before the reductions fully took hold.

The Rome mint was the sole producer of Neronian aes at this stage. Lugdunum had ceased bronze production by this period, making attribution straightforward — and surface patination on surviving examples frequently reflects the acidic soil conditions of Italian archaeological contexts.
