I read
obv. legend slightly differently, unfortunately it's somewhat obscured by doublestriking at 8-9 and 1-2 o'clock:
IMP CAES TRAI (?) HADRIANVS AVG
P MAX (?)
TRI POT COS III P P
Hopefully you will be able to ascertain the correct reading of the doubtful sections with the coin in hand!
Attested
obv. legends for Hadrian's
cistophori so far:
a. HADRIANVS -
AVGVSTVS P P or
AVGVSTVS - HADRIANVS P P
b. The same two legends without P P
c.
IMP CAES TRA (or TRAI) - HADRIANO
AVG P P on the coins attributed to the
Koinon of
Bithynia, with either
COM BIT or just
COS - III on
rev.So the
legend on your coin is certainly new. It is somewhat similar to the Bithynian
legend, but also different because with
P MAX TRI POT COS III added, in the nominative not dative case, and continuous rather than broken above the
portrait.
The
mint attribution may be difficult!
Obv. style and
bust type seem closest to Metcalf's
Mint A, Group II, 307-314 on
his pl. 20-21, coins that in the new
RPC 1367-1374, pl. 58, are tentatively reattributed to Cnidus.
The
legionary eagle and standards on your
rev. seem closest to
RPC 1418, pl. 61, attributed to Metcalf's
Mint B, though this
type was unknown to
Metcalf in that group.
