CHANGE is a project funded by the European Research Council (Grant agreement No. 865680) to study the monetary history of Asia Minor from the beginning of coinage to the coming of Rome. The CHANGE typology is a high-level typology of the coinage of the region created on the principles of Linked Open Data and according to the standards of the nomisma.org project. It provides a typological overview of all ancient coinages from the regions of Asia Minor. This portal will eventually provide access to relevant issues from the Hellenistic Royal Coinages Portal created by the ANS, of Mysia and Troas created by the Corpus Nummorum project of the SMK Berlin and BBAW, and to an extended and elaborated version of the typology for the remainder of Asia Minor provided by the IRIS project of the BnF and CSA at Oxford University.
