I am offering a Roman Antoninianus for exchange:
Postumus (260–269 AD), Antoninianus, Treveri mint
Obverse:
IMP C POSTVMVS P F AVG
Radiate, draped and cuirassed bust right
Reverse:
SERAPI COMITI AVG
Serapis standing left, raising hand and holding sceptre
I am mainly looking to exchange it for non-Roman ancient silver coins, especially Greek, Parthian, Sasanian, Hephthalite, Byzantine, or other ancient issues.
I am open to fair swaps based on condition and rarity.
International swaps are welcome.
I can provide additional photos if needed.
