Augustus, Rome mint, issued by an unclear moneyer, struck 7-6 BC.,
As (ø 24-26 mm / 6,84 g), copper, axes about medal alignment ↑↑ (ca. 350°),
Av.: [CAESAR AVGVST PONT M]AX [TRIBVNIC – POT] , (legend starting at 7 o´clock) / CAE , his bare head facing right, countermark CAE before head within rectangular incuse.
Rv.: [... III VIR AAA FF] / S·C , legend around large S·C.
cf. RIC I, 427-442 .
For countermark: cf. Werz 61.1
The coin must have been struck by Agrippa, Tullus, or Otho in 7 BC; or Silanus, Quinctilianus, or Messalla in 6 BC, because only these two colleges of moneyers struck asses for Augustus after 12 BC when he assumed the title Pontifex Maximus.
