Thanks @Deacon Ray and @ancient coin hunter. The comet Coin was a clever propaganda device - Augustus purportedly claimed that the comet (which had recently appeared in the sky) was a heavenly manifestation of the Devine spirit of Julius Caesar ascending to reside with the Gods - and thus inferring his own divine association.
I am not surprised that these coins were used for decorations. Mine still has part of the iron nail that held it to something.
One of my favorite denarius with a youthful Augustus portrait. Nothing is perfect :-( a little bit of center, a few scratches on the obverse and corrosion on the reverse: Rome 13 BC, C. Antistius Reginus moneyer, who was also a friend of Cicero RIC I 410, 17 x 18 mm, 3.83 g Obv.: CAESAR AVGVSTVS Head of Augustus, bare, right Reverse: C • ANTISTIVS • REGINVS VIR • III sacrificial implements: Simpulum and lituus above, tripod and patera below
Thanks, Deacon Ray, for posting these beautiful coins. You have inspired me to buy some Augustus coins as well.
