The following commentary is a (quick) translation from CGB about a similar coin :

"Although Augustus associated his close friend Agrippa in his coinage, he didn't for him alone. Gaius honoured the memory of his grandfather, recalling he had been COS III in 27 BC while Augustus was COS VII at the same time.
Gaius, however, as the new emperor would like us to remember his double filiation : Through his father, Germanicus, he's descended from Nero Drusus and Antonia, thus from Tiberius ; through his mother Agrippina the elder, he tells us Agrippa and Julia are his grand parents and he's a grand grand son of Augustus. Agrippa remained prestigious all along the first century CE, although he had died 12 BC. Titus then Domitian will also strike this type, seemingly very succesfull towards population (see RCV 2589 and 2894)"
