Yes, Pater Patriae, a title awarded to Augustus in 2 BCE. It appears only on the Type 4 coins, Sear 1731. See the multicollect.net link I posted above.
Thank you. Since there are two busts, in Janiform style, and of equal size,, I would assume that the plural Patres Patriae, Fathers of the Country, would apply in this instance?
Interesting. Since the Roman Senate bestowed this title on August in 2 BCE, and these coins were produced circa 10-14 BCE, there seems to be some ambiguity due to the way Agrippa and Octavian (Augustus) are portrayed on the obverse. Could this honorific title apply just to Augustus or to both August and Agrippa? Was there any reference of this title used unofficially for Augustus prior to 2 BCE?
I see. So this type 4 must have been produced 2 BCE or later, since I doubt the honorific title for Augustus would appear on a coin without official approval. It takes me an hour or two to catch on. Thanks!
At https://www.davidrsear.com/academy/roman_legends.html you can read: "P P = Pater Patriae, 'Father of his Country'. Augustus received this title in 2 BC and it was subsequently adopted by most of his successors at the time of their accession. An earlier version (Parens Patriae) had been bestowed on Cicero after his exposure of the Catiline conspiracy in 63 BC and on Caesar in the final months of his life."
