This coin is part of the famous coded Eqviti series (see the first letter "I" in left field, which is the 4th letter of the EQVITI word struck by the 4th officina, i.e. officina "Q"), discovered and first published by Alexander Missong in his articale ‘Gleichartig systemisirte Münzreihen unter Kaiser Probus’ (1873).

There were 6 officinae at the Ticinum mint at that time; each one struck a different reverse with a different letter from the EQVITI code in the left or right field:

E/-//PXXI (Concord Milit - 1st officina); 

Q/-//SXXI (Provident Avg; 2nd officina);

V/-//TXXI (Salvs Avg; 3rd officina);

I/-//QXXI (Marti Pacif; 4th officina);

T/-//VXXI (Pax Avgvsti; 5th officina);

-/I//VIXXI (Secvrit Perp; 6th officina)
