Salonina AR Antoninianus. Milan mint. 

Obv: CORN SALONINA AVG, diademed and draped bust right, on crescent
Rev: IVNO REGINA, Juno standing left, holding patera and transverse sceptre. 

RIC V-1, 58; Sear 10672 var (obv legend).
Note: The main visual difference between RIC 58 of Milan and the 
seemingly identical RIC 28 of Rome, is the way that the letter N is 
engraved. The letter N in the Rome mint was normally engraved as "III" 
(similar to the "IIII" for "M" on coins of Claudius and Gallienus). 
Milan used the more usual N or IV shape.
