Valens "AE3".Well, not so fast.
This obverse legend for Valens is in RIC only for gold and silver, never AE. That's one dimension of rarity--a not-in-RIC AE legend. (It took a lot of looking in RIC to confirm that assertion.)
The reverse fieldmarks are in RIC only after the death of Valens. They begin with the next issue for which SECVRITAS REIPVBLICAE has been discontinued except for one "r5" example for Gratian. (RIC IX Antioch 49). This coin is from that issue (which is not listed as having any Valens coins) of slightly smaller size AE3 coins, which are mostly CONCORDIA AVGGG coins which were not issued for Valens. It has the smaller size it should have to belong to that issue.
If it took me almost an hour of looking to identify what I had, you can see why the seller didn't bother. 99 times out of 100 he would not have found anything special. I got lucky.
