Photo of a coin sold the 14/01/2003 by Classical Numismtaic Group, Triton VI, lot 1137, link to the sale: https://www.acsearch.info/search.html?id=122081, link to their website: https://www.cngcoins.com/.
No cross visible on the shoulder, the illustration in RIC X appears to show a Latin cross. Variant? To be confirmed, the photo in the RIC X is of very poor quality and does not allow the presence of a cross to be concluded.
The RIC X note for this n°209, age 3742: ''2091, 2092 reverse die link''. Therefore linked to a coin of Valentinian III. I observe that the two copies illustrated in the RIC X do not share the same reverse die. These must be other coins seen.
