After posting my Porta Nigra, here is the man who ordered it - nothing spectacular, but perfect for me: a clean, round, cheap but handsome and "Tiber"-toned Sestertius M AVREL ANTONINVS AVG ARMEMIACVS PM / TR P XVIII IMP II COS III S C Laureate head right / Virtus standing right, holding spear and resting hand on shield Sestertius, Rome 164 32 mm, 21 gr RIC 861, C 838, BMC 1088, Banti 449
Nicely centered and with a lot of eye-appeal! Here's one with the Salus reverse: Marcus Aurelius, AD 161-180 Æ Sestertius , 23.16 g; 29.5 mm Rome mint, AD 169 Obv: M ANTONINVS AVG TR P XXIIII, laureate bust right Rev: SALVTI AVG COS III SC, Salus standing left, feeding snake arising from altar and holding scepter Refs: RIC 964; BMCRE 1351; Cohen 544; MIR 182; RCV 4998.
Yes, perfect centering, and although I generally prefer tan or green patina, I find that one quite appealing.
