Sestertius - Tiberius PERMISSV Q IVN BLAESI PROCOS IT C P GAVIO CAS D D C I P

This piece was struck in 21 AD under the authority of Quintus Junius Blaesus, the proconsul of Africa Proconsularis — and uncle of Sejanus, the notorious praetorian prefect who was then consolidating power in Rome. Blaesus's tenure in Africa was distinguished by a protracted campaign against the Tacfarinas-led Musulamii revolt, for which Tiberius awarded him an imperatorial salutation, one of the last granted to a man outside the imperial family.

Colonial bronze issues of this period from Africa Proconsularis are among the more complex products of provincial minting, dependent entirely on the proconsul's explicit permission — hence the PERMISSV formula in the legend.
