This coin share the same obverse die as the copy preserved at the museum of Berlin, Ident.Nr. 18213723. I report a copy with same dies sold on the sale ''Platt, vente numismatique du 17 et 18 mars 1970, Catalogue de vente de monnaies romaines et Byzantines de la Coll. du Docteur H. Longuet, hotel drouot'' lot 238. Here is the photo:

The only difference between AYC # 2, RIC 1804 and AYC # 2 obv. link, RIC 1808 is the obverse die. Indeed, the RIC X mentions that the RIC 1808 has the same obverse die as a coin minted in Roma. I did not find a different die (except the one illustrated in the RIC plate 47 n° 1804 (AYC #2)) from that of the AYC # 2 obv. link, RIC 1808 which is therefore linked to Roma. To sum up, I found two different obverse dies as well as two different reverse dies for this mint. Obverse 1 and Reverse 1: AYC # 2, RIC 1804. Obverse 2 and Reverse 2: AYC # 2 obv. link, RIC 1808.

Here is the other coin struck in Roma and sharing same obvers die:

All Solidi of all types and in all mints (except the one in Constantinople) always display a double pearl necklace. Except for AYC # 7 (see comment). This little detail may make the difference with the smaller denominations.

A ribbon emerges from the two letters G on the obverse. Common thing with the mints of this region for this period.

The jewels on the cross on the reverse are probably erased by wear, a dot in an arch is at the base of the cross (only die seen with this feature). See comment AYC # 9 var detailing a coin with a smooth cross as well.

On the reverse I noted ''Angel'' in the description. We can also say that this is Victoria but the image of the victory at that time had indeed become that of an angel symbolizing the Christian victory. I note that this character is probably also a representation of the Empress in the guise of the angel. Indeed, the character often wears the same double pearl diadem and the clothes are decorated like those of Galla Placidia. I have noticed many times that on the coinage of various Empresses the character on the reverse is depicted as the Empress.
