Watch List notes:

The Roman Empire
Marcus Aurelius augustus, 161 – 180

Denarius 179, AR 3.06 g. M AVREL AN – TONINVS AVG Laureate head r. Rev. TR P XXXIII – IMP X COS III P P Mars standing r., holding spear and leaning on shield. C 970. BMC 786. RIC 406.
Old cabinet tone and extremely fine

One of the last portraits issued during Marcus' lifetime. I am tempted to see a depressed and tired facial expression, but this is likely just our knowledge of the difficult time he faced during the final years of his northern campaign. AMP.
