The American Numismatic Society and the Institute of Archaeology of University College London, U.K., have launched an important new tool for the analysis of Roman Republican coin hoards.

Coin Hoards of the Roman Republic Online (CHRR Online) is a collaboration between Rick Witschonke and Ethan Gruber at the ANS and Dr. Kris Lockyear of UCL.

The new web-based tool makes available in searchable form the contents of a database created by Dr. Lockyear of 694 Roman Republican coin hoards and the 115,000 coins that they contain. The new tool, which is based on the Numishare technology, makes it possible to browse, search, map and analyze the evidence of Roman coin finds in new ways.

“The database was initially created on a PC for my PhD, but it has continued to be expanded since then and forms the basis of my book, Patterns and Process in the Late Roman Republican Coin Hoards, where it is used, amongst other things, to investigate the size of late Republican coin issues, the date of the import of Republican denarii to Dacia and the patterning created by the events of the civil wars,” said Lockyear. “I am very grateful to Professor Michael Crawford for allowing me access to his unpublished archive held in the British Museum.”

The creation of the new web tool was the work of ANS database developer Ethan Gruber. The integration of Roman Republican Coinage coin types defined by into CHRR Online enables maps and timelines showing the geographic and temporal extent of hoards. Users of the quantitative analysis interface may compare the distribution of selected typological attributes across numerous hoards, visualizing results in the form of graphs or downloading data in CSV for more sophisticated analyses.
