Constantius II, AE17. 

Obv: DN CONSTAN-TIVS PF AVG, , pearl diademed (broad band type), draped, 
 cuirassed bust right 
Rev: FEL TEMP RE-PARATIO, soldier spearing fallen horseman who is bearded, 
 bare-headed, his arm reaching directly upwards. 
Mintmark CONSH; Epsilon dot in centre. 

RIC VIII Constantinople 126, rated rare. 

Notes: I have never seen one of these before, with the horseman's 
arm absolutely upright. The Epsilon is smaller than usual  because 
there is not much room between the spear and the soldier's knee. 
There is also a smaller dot (not dirt) just above the horse's back. 
Also note that the diadem is different than normal, more like a 
pearled band than a double row of pearls.
