(1) First Series, c. 30-28 BC. AE 25, 18.42g. Bare head of Octavian right / Eagle standing left between cornucopia and Π. RPC 5001 (29 spec.), Dattari-Savio pl. 1, 2 (this coin). (2) Second Series, after 19 BC. AE 25, 11.30g. Bare head right / Vase of oenochoe form, with spout on left. RPC 5005 (19 spec.). A Large Collection of Roman Provincial Coins Struck at Alexandria in Egypt, Donated to the Art Institute of Chicago in 1978-1984 by Robert L. Grover, and Containing Many Pieces Deriving from the Giovanni Dattari Collection, the Most Complete Collection of Alexandrian Coins Ever Assembled Each coin, even those in the large lots, is accompanied by a square ticket, 1 5/8” (41 mm) wide and high, on which the following information is recorded: the Art Institute’s acquisition number, always beginning with the year of donation, between 1978 and 1984; a brief description of the coin, with its date (regnal year) but not transcribing its obverse legend; one or two references to standard catalogues, usually BMC and Dattari; and, occasionally, a note of the coin’s provenance, “ex Dattari Collection”. Quite a few of the tickets also cite more recent reference works, added by Harlan Berk’s cataloguer in preparing the coins for auction; for example Angelo Geissen’s Cologne catalogue (Cologne), Roman Provincial Coinage (RPC), and the volume of Dattari rubbings, with introductory material and some cataloguing by Adriano Savio (Dattari-Savio). It is curious that of the 139 coins stated by their tickets to derive from the Dattari Collection, about half could indeed also be located in the Dattari-Savio volume of rubbings, but the other half could not be found there. Since it seems unlikely that either the donor Robert L. Grover or the dealers from whom he bought were fabricating Dattari provenances, it would appear that the Dattari Collection included quite a few coins that are not illustrated in the published volume of rubbings, presumably because they were acquired after those rubbings had been made. Perhaps thirty or forty additional coins were noted by the cataloguer to derive from the Dattari Collection, because rubbings of them are shown in Dattari-Savio, though this provenance had not been recorded on their tickets. It seems likely that Dattari provenances remain to be observed for some other coins in the collection too, since the cataloguer did not check many of the commoner coins against the rubbings.
