Exe: R[thunderbolt][Delta] Rome mint: AD 281 = RIC Vii, p. 37, 187; Cohen 528 Guaranteed genuine. Marcus Aurelius Probus was Emperor of Rome from 276 to 282 AD. 
The army proclaimed Probus Emperor in opposition to Florian who was soon murdered by his own troops. He is, perhaps, the best example of the soldier emperors that ruled Rome during the last half of the Third Century AD. He spent most of his reign involved in military affairs, suppressed several bids for power by usurpers and died at the hands of his own disgruntled soldiers. It would seem his fatal error to have made a statement that the time was coming when a state of peace would make the armies unnecessary. In the words of Doug Smith (http://dougsmith.ancients.info/probus.html), It is never a good management technique to tell the workers that you don't need or appreciate them. When your workers carry swords, this was to be a big mistake. 

----------
(1) Secondo il RIC, non è possibile datare la moneta in maniera precisa. Invece Karl Pink, nel sito: http://www.i-numis.com/rome/articles/probus/probus2-fr.html sostiene che la moneta appartenga alla sesta emissione della zecca di Roma e sia stata coniata nel 281 d.C.
(2)PROBVS Pivs Felix AVGvstvs. Elementi sulla vita di Probo vengono forniti in altra pagina di questo sito. La leggenda corta (priva cioè delle praenomen IMP) è comune per la zecca di Roma
(3)ROMAE AETERnae. La moneta è dedicata all'eternità di Roma.
(4)L'esergo della moneta non è completamente leggibile per cui non è possibile determinare quale fosse la lettera posta nella parte destra dell'esergo, dopo il fulmine. Tuttavia la classificazione RIC V/II 266 è ugualmente valida perché i due casi non vengono distinti.
