I would be interested in seeing the Leguto article.
I have a list of about 20-21 theta coin
types. They are from a different die carver than the normal
Gallienus coins, but might be by the same die carver as the
Salonina coins of years 11-15. It is the first I have heard that they were minted in Thebes.
When
Gallienus was recognized during years 8 to 9, with
Macrianus and
Quietus in their year 1=year 8 of
Gallienus, is
still not certain.
What I see is the following:
LH -- joint reign issues of
Valerian I,
Gallienus,
Salonina and
Saloninus (all extremely
rare)
Some year 8 dies were modified from LH to LA -- After which coins of LA for
Macrianus and
Quietus were issued (
style of the Valerian family tetradrachms). There are no year 2 issues.
LH sole reign tetradrachms of
Gallienus (
obverse inscription changed for the sole reign).
LTHETA issues of
GallienusLHA sole reign of
Gallienus. It was assumed by
Milne that LHA was issued in year 9 as the date was modified from Ltheta (
obverse dies better than LTHETA ones)
Then LENATOV issues of
Gallienus.
The papyri evidence is very confusing and does not seem to support
Gallienus being recognized in year 8 of
his sole reign.
