The original Inventory of Greek Coin Hoards (IGCH), edited by Margaret Thompson of the ANS, Otto Mørkholm of the Danish cabinet in Copenhagen and Coin Kraay of the Heberden Coin Room in the Ashmolean Museum, Oxford, was published in 1973 by the ANS for the International Numismatic Commission. The work contains inventory listings of 2387 hoards, covering the whole of the ancient Greek numismatic world.
Online IGCH was devised by Sebastian Heath and Andrew Meadows as an attempt to create an open and accessible version of IGCH on the world Wide Web using the principles of Linked Open Data. The test version was housed within the Nomisma.org namespace before its migration to its own domain in February 2015.
Work on the original project was enabled by funding from the American Numismatic Society, Stanford University, and the UK’s Arts and Humanities Research Council. Data was contributed by the Nomisma project based at Paris IV Sorbonne. Subsequent work to create the new site has been supported by the International Numismatic Council, under whose auspices the project has now been incorporated. Technical realisation of the new IGCH site is by Ethan Gruber.
The current site is a prototype, and will undergo enhancement through the course of 2015. It is the long-term aim of the project to incorporate all published Greek coin hoards as part of the broader Online Greek Coinage initiative.
