Extremely rare and desirable obverse legend with the PERPETVO title. Probus was the only roman emperor to use this title in the whole Roman coinage; the only other close analogy would be the Dictator Perpetuo title bestowed upon Julius Ceasar in the year 44 BCE). Only the 2nd example of this exact variant known!
