The
obverse is difficult to interpret. I cannot fond another die by this celator. The horisontal crest end is used by just a few celators (one or perhaps two) at
Rome at this time. One might think that this is a bronze trial strike for a gold coin, but
Constantine is not known to have been in
Rome anytime near (and gold was almost exclusively struck where the emperor was). In my view, it is a regular bronze coin of the P R /RP series, but I could be wrong.
The P R /RP series shows considerable experimenting. For reasons unknown to me, the
mint of
Rome had the opportunity to experiment with
types lacking precedence in Constantine's coinage. An example: the so-called
camp gates (which they are not, of course)
had a long
history before
Constantine. The
mint of
Rome, however, played with a completely new
type, the 3-D gate. Two examples are shown here.
Only a comprehensive die study can shed light on which of the varied
types were struck together. Knowledge of that might, perhaps, give clues to the broader message that
Constantine wanted to transmit. If there was such a message. In any case, the die study is on its way.
