In the words of Curtis Clay: "The very rare earliest issue of Procopius' bronze coinage, not only continuing Valentinian's reduced weight standard and copying his right-facing portrait, but also taking over Valentinian's reverse legend SECVRITAS REIPVB, combined with Procopius' normal type of emperor standing. Only two specimens of this coin seem to have been recorded until now: that published by W. Weiser in Money trend 1977, pp. 8-12, which was later sold in Schulten Sale, October 1984, 771; and a second in BM mentioned by Weiser. Our specimen may be the third recorded. Very soon, Procopius introduced his own reverse legend, REPARATIO FEL TEMP, to replace that of Valentinian; soon after that, he reintoduced Julian II's heavier standard for bronze coins and changed the direction of his obverse portrait from right to left. Most of Procopius' surviving bronze coins belong to this large last issue, on Julian II's standard and with portrait facing left."
By now there are a couple of dozens known of this type.
