I forgot to post this one.
Constantius II
A.D. 352-355
Ӕ nummus 21mm 3.6g
D N CONSTANTIVS P F AVG; pearl diademed, draped & cuirassed bust right.
FEL TEMP REPARATIO; Soldier spearing fallen horseman, LXXII in left field, Chi-Rho in center.
In ex. AQP
RIC VIII Aquileia 195
This FEL TEMP has a Chi-Rho on the reverse in the center. It is in rough condition but is actually fairly rare (much rare than coins from Gallus) despite the RIC rating of common.
LXXII is the weight standard (72 to a pound) and also appeared on coins from Siscia. These were issued shortly after Constantius II reclaimed Aquileia from Magnentius.
So this coin checks several boxes
--Rare
--Chi-Rho
--One of the few instances with a weight standard on the coin
--historical significance…marks the recapture of Aquileia from Magnentius
