Florianus Emperor of the Roman Empire from 276 to 276.
Marcus Annius Florianus Augustus was Roman Emperor for a few months in 276.

He was reportedly a maternal half-brother to the Emperor Tacitus - and as the appointed Praetorian Prefect in Tacitus's army in his campaign against the Goths, he was chosen by the army in the West to succeed Tacitus in 276, without the consensus of the Roman Senate.

The army in the East elected Probus emperor, and the two rival emperors met in battle in Cilicia. Florianus had the larger army, but Probus was a more experienced general and likely secured a small victory. Florian was then assassinated by his own troops near Tarsus once their confidence was lost.

He died in September 276, having been emperor for only eighty-eight days.

Silvered (probably tinned actually) AE Antoninianus (technically an Aurelianinus, but virtually no one uses that term)

So the obverse inscription varies from RIC 111 on the ANNIVS bit, RIC 111 is just ANN.

The head on the figure of Aeternitas appears to be animal-like, whether this is by accident or deliberate is up for debate! Some have suggested it may reflect the personal religious standing of the engraver (perhaps it is Roman-Egyptian hybrid; some have suggested the head looks remarkably like Anubis). A week before I bought the coin the following discussion appeared online: https://www.cointalk.com/threads/fascinating.314418/ Whatever the story behind it, there are few, if any, coins of Florian like this one out there.
