Don...
PS: Guessing the reverse shows Potumus holding globe (visible orb) and spear.
The image and legend on the other coin (right side bottom pic) is consistent (at least through these old eyes) as being attributed to this coin:
Postumus Antoninianus, struck 262 AD at Cologne mint.
Obv: IMP C POSTVMVS P F AVG, radiate, draped and cuirassed bust right.
Rev: IOVI PROPVGNAT, Jupiter standing left, holding thunderbolt and sceptre.
RIC 70; Elmer 290; AGK (corr.) 36; Cunetio 2402;
![]()
The "OP" and "NAT" are evident in the reverse legend.
