Corpus Nummorum Online


Corpus Nummorum Online is a web portal devoted to the ancient coins of lower Moesia, Thrace, Mysia and the Troad. This is a pilot project for assembling ancient Greek coinage by region and mint for the various purposes of research and cultural heritage preservation. The research database is based primarily on Berlin collections, which include coins from approximately 104 mints from the aforementioned regions in the Münzkabinett Berlin, as well as an extensive collection of plaster casts that were made from coins in various collections worldwide and deposited at the Berlin-Brandenburg Academy of Sciences and Humanities (BBAW). These datasets will be further supplemented by digital museum catalogues and material from other sources. In line with the concept of public science, the portal also offers the possibility of augmenting the database by registering coins externally. The database makes it possible to sort individual coins systematically and group them by mints and types, as well as by dies that were used in the minting process. If needed, types can also be subdivided or arranged into larger groups, such as series or issues. All coins in the portal are scientifically described in both German and English. Standardised criteria for the description of coin images, both for coin types and individual specimens, have been developed (for the description guidelines, click here or use the Help button). As a collective endeavour of the Berlin-Brandenburg Academy of Sciences and Humanities, the Münzkabinett der Staatlichen Museen zu Berlin, and the Big Data Lab of Goethe University in Frankfurt am Main, the portal is being developed in close collaboration with other international initiatives for the typological presentation of Greek coins in the Semantic Web, such as the Online Greek Coinage project, which is under the patronage of the International Numismatic Council ( All relevant database fields are linked to stable Uniform Resource Identifiers (URIs) of numismatic concepts ( Because the portal is funded through various external-grant projects, there is variation in the scope of the data and the depth of coverage, but the overarching goal remains consistent: to create type catalogues for each respective coinage.


126 BnF coins integrated into Antigonid Coins Online

BnF Antigonid Coins Online

One hundred twenty-six coins from the Bibliothèque nationale de France, recently cataloged by Julien Olivier, have been incorporated into the newly-released Antigonid Coins Online (AGCO), which so far includes the coinage of Demetrius Poliorcetes. Roughly a dozen of these coins were already accessible through AGCO upon its launch since a handful of the coins of Demetrius are cross-linked with posthumous issues in the name of Alexander the Great in PELLA (related specimens are displayed in Numishare when they link directly to a type URI or implied to be the same via skos:exactMatch).

There are now 433 total specimens connected to the 182 types of Demetrius Poliorcetes. Two-thirds of the types are connected to at least one physical specimens, and about 40% (77 types) of the corpus links to at least one photographed coin. This number will grow, as the majority of the ANS’ coins of Demetrius have not been photographed yet.


Seleucid Monograms published to SCO

Seleucid monogramsEthan Gruber, the Web Services Developer for the American Numismatic Society, has published around 1,300 monograms appearing on the coinage of Seleucus I through Antiochus III (Houghton, Lorber, and Hoover’s Seleucid Coins, Part 1) to the Seleucid Coins Online (SCO) project. These monograms are linked to thousands of types and subtypes.

According to Gruber, where the SCO monograms differ from the previous projects is that monograms have been organized hierarchically by Oliver Hoover. Unlike in PELLA and PCO, where a monogram usually has one SVG file (but may have more than one to illustrate slight variations in style), the Seleucid monograms have been grouped thematically by letters and general design motif.

Coin Hoards of the Roman Empire


The Coin Hoards of the Roman Empire Project is a joint initiative of the Ashmolean Museum and the Oxford Roman Economy Project. It is the brainchild of Baron Lorne Thyssen-Bornemisza and is funded by the Augustus Foundation. It intends to fill a major lacuna in the digital coverage of coin hoards from antiquity. It aims to collect information about hoards of all coinages in use in the Roman Empire between approximately 30 BC and AD 400. Imperial Coinage forms the main focus of the project, but Iron Age and Roman Provincial coinages in circulation within this period are also included to give a complete picture of the monetary systems of both the West and the East. In 2019 the scope of the Project was extended to include hoards of Roman coins from outside the Empire. The intention of the Project is to provide the foundations for a systematic Empire-wide study of hoarding and to promote the integration of numismatic data into broader research on the Roman Economy.

PELLA: Philip II Gold and Silver Coins


After considerable effort by ANS curator Peter van Alfen, the gold and silver coin types of Philip II of Macedon have been published to PELLA. This typology, based on Georges Le Rider’s 1977 Le monnayage d’argent et d’or de Philippe II frappé en Macédoine de 359 à 294, has been numbered 1-382. Le Rider’s corpus is actually a die study, and the numbering system is based on die combinations rather than types. As such, there are about 2,200 or so die combinations that correspond to the 382 types. These types were given a new numbering scheme, pella.philip_ii.1 to 382, but all of the Le Rider numbers are also URIs in order to establish a concordance between Le Rider and the new scheme so that collections that cataloged their coins with Le Rider numbers can submit their RDF with those URIs or map the Le Rider to the PELLA type number.
