I don't have a Roman Oath Scene, but I have the Marsic Confederation Oath Scene representing the Eight Tribes in Rebellion.
I'm missing that as well......and I think I recall seeing yours (or one similar--the auctions are overloading my brain LOL) and I'll be after that type for months yet to come. I 'swear' those oath coins are tough to win
Marsic Confederation - Social War 91-88 BCE Marsic Confederation / Italian Allies Social War 90-88 BCE AR Denarius 19x17.9mm, 3.7g Anonymous Issue, Corfinium Mint Obv: Italia head, l, ITALIA behind Rev: Oath-taking scene with eight warriors, four on each side, pointing their swords towards a sacrificial pig, which is held by an attendant kneeling at the foot of a standard. Comment: The reverse is based on the gold Stater and Half-Stater from the Second Punic War Ref: Sear 227; SYD 621 Rare Comment: The oath taking scene presumably refers to the oaths between the 8 members of the Marsic confederation: Marsi, Peligni, Piceni, Vestini, Samnites, Frentani, Marrucini, and Lucani.
There are no coins from the time of the founding but Romulus as an adult does appear on this Hadrian denarius.
I think, with an olive branch, the Roman god of war is celebrating the birthday of a new era of peace and love for all the peoples under Roman rule.
