Well this little gem arrived today, and I'm very pleased to have an example of this scarcer type in such a decent grade... And a lovely, even shade of green.
I saw that when it came out, an interesting read for sure. I just draw a distinction between Martin's serious scholarship and some guy (no offence intended) randomly posting a medal with a sexually explicit pose. I'm not exactly Bible thumping here Steve, just expecting that when semi-pornographic material is posted it is done so with scholarly intent and explanation, not a happy face.
I scoured RIC VIII for any instances of this reverse type, and discovered that it is only recorded for the mints of Aquileia, Siscia, and Sirmium. There is another scarce Victory type, with Victory advancing left, holding wreath and palm branch, but I'm speaking only of this particular representation: Victory advancing left, looking right, holding a wreath in each hand. Aquileia 74 CONSTANT-IVS P F AVG, Officinae P, S, T; Group I, Series I, c. 345 75 CONSTAN-S P F AVG, Officinae P, S, T, Group I, Series I, c. 345 Siscia Sirmium 25 D N CONSTAN-TIVS P F AVG; VICTORIA AVGVSTORVM; SIRM; R; Group I, 351-355 Notice that the Sirmium coin spells out the abbreviation AVGG. And it would appear that this representation of Victory (during this period) only occurs on the coins of Constantius II and Constans. So, just a little bit of cherry-picking information for anyone looking to acquire some of the less common Constantines.
JA I liked your coin so much I bought the Constantius version today. Mainly because it looks like Victory is pumping iron.
