The reverse of this coin is rough; but the interesting stuff is on the obverse. The bust is laureate and draped, with no hint of cuirass and the obverse legend is odd, ending with N CS, a shorter version of RIC 28 which ends with NOV CS, following the same pattern for Licinius II. This legend was probably an attempt at "noble Caesar"... RIC offers this --
“…Maurice's explanation of the obverse legends as due to the Greek engravers of the mint is probably correct. All the same, we should not expect such grossly distorted versions of the official legends to appear at a time of normal friendly intercourse between the two parts of the Empire. The coins should therefore be regarded as an endeavour to commemorate the settlement at Serdica at an early stage before proper instructions had been circulated to all the mints.” RIC VII pg. 595
