Not published that I know of, but I
had a worn specimen of such a
sestertius in my first
collection over twenty-five years ago.
When
Oxford purchased the pre-193 portion of my first
collection c. 1990, I was surprised that they returned this coin as a duplicate of one they already
had! And indeed, they did have another one, from different dies than mine. I made them a gift of mine, since it was
still of interest for the variant dies, and deserved to remain with the specialty
collection I
had formed of the bronze coins of
Antoninus Pius in 138-9.
A couple of years ago I acquired a variant specimen: from the same
rev. die as Oxford's first coin, but with later
obv. legend IMP T AEL CAES HADRI A - NTONINVS
AVG PIVS,
Head laureate r.
Your specimen is a new combination of dies already known to me.
Rev.: same die as the coin in my first
collection, now in
Oxford.
Obv: same die as a coin in Klosterneuburg just
north of
Vienna, which has the same
Pax standing
rev. type, but
legend PONT MAX TR POT COS S - C.
So including your coin, this form of titulature is now known on four
sestertii, coming from just two
reverse dies.
