Well this is all I have personally found, however I don't feel that it matches very well... Can someone come up with a more exact ID Ref: match for this scarce coin? 23.0mm / 6.4gm. Thanks in advance Septimius Severus, AE23 of Philadelphia, Lydia. 193-211 AD. AV KAI CEOVHΡOC, laureate head right / ΦIΛAΔ-EΛΦEΩN above and beneath she-wolf standing right, suckling the twins Romulus and Remus. Philadelphia--BMC Lydia 77.
One from acsearch seems a different reverse die but possibly an obverse match https://www.acsearch.info/search.html?id=2379164
