Bronze Roman As? Which Emperor?

To aid in the search, what do you folks think is across his shoulder on the reverse?

I believe you have it Bob! That "OR" is quite clear. Matches weight for this coin below:

Good work Bob - this had me totally stumped.

Very interesting coin, too. Rome destroyed Corinth in 146 BC (killing all the men and enslaving all the women) and it stood in ruins for 100 years until it was refounded by Caesar as Colonia Laus Julia Corinthiensis. The city was rebuilt in monumental fashion and flourished for centuries until it was substantially destroyed by successive earthquakes in the late 4th century, followed by barbarian invasions. The roman city went to ruins, with only a small town surviving there, but the city proper transferred to the Corinthian acropolis (Acrocorinth) where it survived until it was removed in the 19th century.

I didn't think anyone would get this - Bob you really came through - again. Ben as always love your mini history lessons - truly!
