I
hope I can
help you a little with this question.
As for the mints of the
postumus, opinions are
still fundamentally divided. Without reliable knowledge, I don't want to step on anyone's feet.
In principle, it would also be possible for an
mint, to change a location with
his staff and employee during this troublesome time. So that you couldn't tell a difference stylistically, in relation to
Cologne and Treveris, for example.
It looks different here for the emperors
Victorinus,
Tetricus I and
Tetricus II.. From an archaeological point of view, a
mint in Trier seems to be clearly secured here. If I can take a short quote at the "Trierer Magazine, 71/72-2008/09-Special print".
3.2.2: A dated rubble package on the city wall and questions about the
mint of the Gallic emperors in Trier:
((by Dr. Karl Josef Gilles)/from excavation report from Wilfried Knickrehm.)
Even at an early stage of the excavations, Wilfried Knickrehm noticed a massive accumulation of Antoninians from the time of
the Gallic Empire (260-274 a.d.)under the coins found in this rubble layer. Especially the coinage of
Victorinus,
Tetricus I.,
his son
Tetricus II..
The layers of the earth were measured three-dimensionally on the basis of this. In this way, 78 coins were found in the course of the excavations. 34 other coins were measured for their height above sea level in the location where they were found.
Bronze pieces were found in a height range between about 131.20 m and 129.70 m. Mainly antoninians of
Tetricus I and
Tetricus II..
With a
weight of 2-3g, the majority of them are significantly heavier than their imitations made in the local mints.
With the year 274, the layer's extensive series of coins breaks off. A total of 320 fully-fledged Antoniniane Gaulish emperors were found in the course of the
work. (around 59% of all
Roman coins found in the excavation, of which around 250 were issued by
Tetricus I and II.)
Along with the coins, bronze residues and a
bar were found. About 40 raw and intermediate products were also found for the production.
Of particular importance was W. Knickrehm's observation, that the
weight of the segments corresponded to that of the regular antoninians found with them. In view of this fact, he was the first to recognize the remains of the Trier
mint from the time of
the Gallic Empire.
