As part of the National Endowment of the Humanities funded Hellenistic Royal Coinages project, Antigonid Coins Online (AGCO) is a new research tool that will provide wide access to the coins listed in various print typologies of the coinages produced by the Hellenistic Antigonid dynasty (306–168 BC). This first version of AGCO, launched in July 2020, features only the coinage of Demetrius I Poliorcetes (r. 294–287 BC) based on the typology published in Edward T. Newell’s 1927 volume, The Coinages of Demetrius Poliorcetes with cross-references as well to those types in the name of Alexander III of Macedon catalogued by Martin Price in his 1991 volume The Coinage in the Name of Alexander the Great and Philip Arrhidaeus . Future versions of AGCO will incorporate the coinages of additional Antigonid kings. While the coins of Demetrius in the ANS collection serve as the core of the current searchable catalogue, links to coins (many of which are unique) in the Bibliothèque nationale de France, the British Museum, the Munzkabinett der Staatliche Museen zu Berlin, and other public and private collections, are also available.
AGCO is a project of the American Numismatic Society co-directed by Dr. Peter van Alfen and Ethan Gruber. The web database, based on the Numishare platform, has been developed by Ethan Gruber.
Substantial work in developing AGCO has been carried out by Prof. Andrew Meadows (Oxford University). Lauren Tomanelli provided assistance in organizing material within the ANS collection and illustrating the monograms. Alan Roche is responsible for the photographs of ANS coins. At the British Museum, Martin Price, former Curator of Greek coins, was instrumental in cataloguing this material. Amelia Dowler is the British Museum's current curator of this series. Prof. Bernhard Weisser and Dr. Karsten Dahmen have catalogued the material at the Münzkabinett of the Staatliche Museen zu Berlin. At the Bibliothèque Nationale de France (BnF) Caroline Carrier catalogued the Alexander types, while Simon Glenn did the same at the Ashmolean Museum at Oxford.
In March 2017, the National Endowment for the Humanities awarded Antigonid 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.
