This is either the Rome mint issue RIC 144(b) or Laodicea RIC 516. What say you? The bust looks like high Roman style to me, reverse could go either way. Obv.: L SEPT SEV AVG IMP XI PART MAX; Laureate head of Septimius Severus to right. Rev.: VICTORIAE AVGG FEL; Victory advancing left, holding open wreath in both hands over shield set on low base.
Here's a Severus ex the @Sallent collection: Denarius of Severus featuring Neptune, most likely commemorating his visit to Britain by sea. Septimius Severus, A.R. Denarius, Rome mint, 210 C.E. 3.3 grams, 19.1 mm Obverse: Laureate head right, SEVERVS PIVS AVG Reverse: PMTRP XVIII COS III PP Neptune standing left, nude but for cloak over left shoulder and right arm, right foot on rock, right arm resting on right knee, trident vertical behind in left hand.
That's Rome. This is my Laodicea.... ex Roger Bickford-Smith Collection, ex Barry Murphy, ex Forvm AC
