Jones, "Dictionary of Ancient
Greek Coins" describes
Dikaiosyne as the Greek equivalent of Justice or
Aequitas, usually shown bearing
scales.
Homonoia, is defined a the Greek equivalent of
Concordia, usually depicted with a
patera, branch or
corn ear. So, neither is clearly your
reverse goddess, who appears to bear a
cornucopia.
Your picture is a
bit grainy and I'm having a tough time making out the regnal date. Is the regnal date of your coin IB (12) or IA (11)?
Emmett 3801 only lists the
Dikaiosyne seated
type in year IA (11). The
Homonoia seated
type is listed at
Emmett 3817 in both years 11 and 12.
However, there is also a "
Tyche seated left on throne
type" listed for
Gallienus at
Emmett 3837 in years 11 and 12.
Tyche is often portrayed with a
cornucopia, and I wonder if this might not be a better
attribution.
Unfortunately, Emmett's
reverse descriptions are quite brief, and my recently ordered copy of
Milne has not arrived yet. There appears to be a
palm (?) to the right of your goddess, and she is also holding something in her extended right hand that I can't quite make out (maybe a
corn ear - which would be consistent with
Homonoia). One of the more descriptive catalogues might describe these other elements and
help with a stronger
attribution.
I
hope that helps.
