Illustrated on www.romancoins.info, section imagines imperatorum.
Nero Claudius Drusus (Drusus major) was the brother of Tiberius and father of Germanicus and the later emperor Claudius. He died after a riding accident near the German river Elbe. All Roman coins depicting his portrait were minted under his son Claudius. As seen from his varying portrait types, it would appear these sestertii were struck in different mints, some in Rome and others in auxiliary mints likely in Gaul and/or Spain.
This coin has a very interesting portrait that, in my view, is of a western mint. AMP.
