Ok, I've had this coin a while, but I've never mentioned it on these forums.

It's a coin made of stone. It's mishapen and has a picture of a emperor (I think). Anyway on the case it says:

Front:

Roman Empire
Valentinian I , 364-375
Bronze AE 3
C.37v

Back:

Victory advancing to the left
Legend: SECRITAS REIPVBLICAE

Help?
