I present for your inspection this very rare example of a type issued for the transfer of mints from Ostia to Arles in the year 313 (there exists a dated example).
[IMP] CONSTANTINVS PF AVG, bust left, cuir., laureate, shield over left shoulder, spear over right
PROVIDE-NT-IAE AVGG, female figure (possibly Moneta) on prow, holding cornucopia, facing what must be the personification of Arles, who is holding a standard (Ben informs me that this may be a symbol of Constantine's Italian victory).
QARL in exergue
RIC Arles 30var.
This particular issue is not listed with this particular obverse type, however I am aware of one other in existance. The symbolism of this type and it's partner, VTILITAS PVBLICA
, simply blows me away. On the VTILITAS issue, Moneta is on prow also, but facing away from the figure (probably the personification of Ostia) on the shore, as if departing. On the Providentiae issue, Moneta is depicted as arriving at Arles. An interesting oddity of my example however: On most of these coins, the figure on shore is not wearing a turreted headress, while on mine, she is.
I will attempt a better scan when I have the chance, in the meantime, this one will have to suffice. Please comment!
