I'm pretty sure this is Diocletian, but I wanted to get a second opinion. The bust is very detailed, but unfortunately the lettering is all but gone. I can see IMP C, but that's about it. Reverse has no letters, but the motif matches a CONCORDIA MILITVM. AE Antoninianus Obv: IMP C....PFAVG. Radiate bust right. Rev: (CONCORDIA MILITVM?) Jupiter presenting globe with victory on top. Diam: 19mm
THANK you! That certainly looks right. If I over-stress my eyes enough I can make out enough letters to preclude Diocletian. Gracias.
