4thC Roman bronze sent for ID

Chris,

This is a nice one – I’ve seen too many which have been attacked by farm chemicals, etc.
This is Constantine I (The Great) and the type is VIRTVS EXERCITI; two bound captives seated back-to-back at base of a standard with VOT / XX in two lines on the banner

Unfortunately, I can’t read the mint mark in the exergue.  I could tell you more if I knew the mint – if you can read some or all of the letters/symbols in the exergue, let me know and I can expatiate.  About all I can say authoritatively is that the type dates to around 320-321 AD, it was mainly produced at Western European mints, and the denomination is “centenionalis”, a denomination introduced by Constantine In ca 319 to replace the dwindling follis. The centenionales were struck (shrinking over time as well, of course) right up to 348 and the reforms of Constantius II and Constans which brought in the Majorina-based coinage to replace the centenionales. The most typical example of the majorina coinage is the fallen horseman FEL TEMP REPARATIO with which you are, no doubt, familiar.

The most familiar example of the centenionalis coinage of the Constantinin era is the GLORIA EXERCITVS, 2 soldiers flanking one or two standards which followed this and a couple other types, appearing about a decade later.
