Jovian 363 - 364  A.D.

Coin Description Jovian, AE 19mm, Grade ??, The coin is well centered but the patina is extremely thin the copper core comes trough in the higher areas and on large parts (the cheeks and the robe on the obverse) the smooth patina is gone and there is a rough texture underneath. On the reverse there appears what looks to be ancient graffiti. VM12, RIC VIII Constantinople 178, RBC 473.
Obverse The portrait is of Jovian a diademed, draped, and cuirassed bust facing left. The legend reads : DN IOVIANVS PF AVG meaning: DN (Dominus Noster /our lord showing the emperor to be the supreme ruler) IOVIANVS (his name) PF (Pius Felix / Dutiful and Wise) AVG Augustus which defines him as the emperor. The legend is broken which is a sign of the highest respect and signifies him as the senior Augustus.
Reverse

The reverse shows a wreath with the letters VOT V which translates as: Votis V which means vows for a successful reign of 5 years. This derives from the Roman custom of offering vows of a certain sacrifice to the Gods in return for the granting of some favor or wish. During his reign, the emperor would offer vows to safeguard the people and the state for a certain period. When the end of this period was reached (in this case 5 years his quinqennalia) he would make the sacrifices in fulfillment of those vows.        (note that they only paid on delivery of the goods )

There appears to be "graffiti" on the reverse I'm quite sure I see the letters F and i to the left and an X to the right of the V (the X is not to clear on the scan). I don't think they're just accidental scratches because there are three letters and they are all placed in the open space to the left and right of the V.
I'm also pretty sure they're ancient because there is no copper coming trough the letters and both site stripes of the F have patina.

Mint The exergue reads CONSPD meaning the fourth workshop, Delta, of Constantinople minted in 363 A.D.
The Entire Story The entire story of this coin would read: Jovian our lord and emperor who promises vows for a successful reign in the next five years.
