From Curtis Clay:-
“A coin like yours, from the same obv. die, was in M&M's Voirol Sale of 1968, lot 385, ex Hall Sale, 1950, lot 1203. A second spec. from that same die pair is publ. by Giard, Lyon, 42/1a, pl. XLIII, Coll. Gricourt.
BMC 809 pl. 38.7 has obv. CAESAR not CAES and a broader portrait on shorter neck.
Paris doesn't have this type on a COS III dup. of Vesp. at Lugdunum, but their As, Paris 812 pl. LXVII, is from the same rev. die as your dupondius!"
