Over the last couple of years I've been exploring coins outside of longstanding
area of interest, the "nummi" of
Diocletian's coinage covered by
RIC VI. I came across this coin in a recent
auction and was surprised to see it carried "SC" in the
reverse field. My
library on this period is rather sparse but it's described as a product of the
Antioch mint and is listed in
RSC (cf 81) and apparently in
RIC (cf 87) but i don't have a copy if the latter for the period. I think I recall hearing something about this years ago when I was a more general collector and have seen the SC on the
posthumous coins of
Vespasian. My, perhaps mistaken, understanding was this the latter use of SC or
ex SC was related to
Vespasian's deification by the Senate.
At any rate, can someone provide an explanation of what's going on here for me? A cite to a reference (esp accessible online) would be great. Thanks very much for any assistance.
NB
Per Pekka's note, I
corrected the RIC/RSC numbers which were incorrect in the OP. Sadly I
had even double checked them before posting (LOL), but such is life. Thank you for catching the mistake.
