 standard between them with bulls head on banners; pine tree over dot over dot

RIC VII Arles 389, rare.

The horned bulls' heads on the banners could refer to Legio VIII Avgvsta 
 (whose emblem was a bull), stationed near Arles at this time. 
 Another similar Arles (second officina) coin of Constantius II with bulls' 
 heads on the banners has also been discovered by this seller.
