More than 660 Ptolemaic coins from the Bibliothèque nationale de France have been added into the Nomisma.org numismatic Linked Open Data cloud and are accessible through Ptolemaic Coins Online and the broader Hellenistic Royal Coinages umbrella site.
There are now about 2,400 Ptolemaic coins in PCO (which includes at this phase the gold and silver coinage of Ptolemy I – IV, ca. 330-200 B.C.), and roughly 75% of these are from the BnF and American Numismatic Society. Therefore, high resolution, public domain images are available for reuse for these objects through IIIF web services. In total, 572 of 984 total Ptolemaic types are linked to at least one photographed specimen–almost 60% of the corpus in total.
