Constantine I, Mars with Victoria on globe

[Nikko]

I have never seen this coin before.

CONSTANTINVS PF AVG
MARTI CONSERVATORI, Mars standing left, Victoria on globe, shield and spear in right hand. TT in exergue.
RIC VI TICINUM 121

[Victor]

Nice...I don't recall seeing an example before

[Genio popvli romani]

I remember one from the first workshop already posted by Nikko on nummus-bible.

When I first saw this new example for sale, I believed that the strange reverse was due to double struck....but in deed not.
