As part of the National Endowment for the Humanities funded Hellenistic Royal Coinages project, Ptolemaic Coins Online (PCO) is a new research tool that will ultimately provide wide access to the coins listed in the print volumes of Coins of the Ptolemaic Empire by Catharine C. Lorber, the first attempt to provide a new, comprehensive standard typology and catalogue for the coinage produced by the Ptolemaic dynasty of Egypt since Ioannis Svoronos’s Τα νομίσματα του κράτους των Πτολεμαίων published in 1904–1908. The print volumes of Coins of the Ptolemaic Empire will eventually appear in four parts: Volume I was published in 2018 covering the gold and silver coinage (Part I) and bronze coinage (Part II) of Ptolemy I (r. 323–282 BC) through Ptolemy IV (r. 221–204 BC). Volume II covering the gold and silver coinage (Part I) and bronze coinage (Part II) of Ptolemy V (r. 203–181 BC) through Cleopatra VII (r. 51–30 BC) is expected to appear in print by 2021. The current version of PCO, released in April 2020, covers the coinage found in Volume I, Parts I and II of Coins of the Ptolemaic Empire. Subsequent updates to PCO will occur when Volume II of Coins of the Ptolemaic Empire is released.
While the Ptolemaic coins in the ANS collection (some 3,371 pieces) serve as the core of the searchable catalogue, an effort will be made to illustrate all types in the database, ultimately with links to coins in the Bibliothèque nationale de France, the British Museum, the Münzkabinett der Staatliche Museen zu Berlin, and other public and private collections.
Users should note that catalogue is searchable both by Coins of the Ptolemaic Empire (CPE) catalogue numbers and Svoronos (Sv) catalogue numbers.
In March 2017, the National Endowment for the Humanities awarded Ptolemaic Coins Online $262,000 as part of the the broader Hellenistic Royal Coinages (HRC) initiative. This grant is issued through the NEH Humanities Collections and Reference Resources program, to be dispersed over three years, to complete the project.
