Coinage of the Roman Republic Online (CRRO) aims to provide in effect an online version of Michael Crawford's 1974 publication Roman Republican Coinage (RRC), which is still the primary typology used for the identification of Roman Republican coin types. Since its publication in 1974 there have been significant revisions to the dating of the series following the discovery of new hoards, but no attempt has been made to reflect these or make any other amendments to the published typology at this stage. The descriptions for these coins are based on the typology set out in RRC, but have been modified to meet the standards of the British Museum’s collection management system. Additional types not in the British Museum’s collection were added to this database by Richard Witschonke of the ANS.
This project takes as its starting point the Roman Republican coins in the British Museum collection. These are published in a dedicated online catalogue prepared in 2010 1 , which forms an update to the 1910 catalogue of the collection by Grueber 2 : http://www.britishmuseum.org/research/publications/online_research_catalogues/rrc/roman_republican_coins.aspx.
We would like to acknowledge the contribution of Michael Crawford to the project and also to thank Michael Sharp of Cambridge University Press for allowing us to use the numbering system of Roman Republican Coinage.
RRC Online is made possible by stable numismatic identifiers and linked open data methodologies established by the Nomisma.org project. Coin type data are made available with an Open Database License. All images are copyright of their respective institutions.
In November 2020, CRRO is beginning to enter a second phase of advanced functionality, integrating die links established by Richard Schaefer in the Roman Republican Die Project. Where applicable, the pages for RRC numbers have been enhanced by displaying die links in tables and network graphs, with the die pairings and numeric counts of specimens downloadable as CSV files for further analysis in other statistical platforms. New specimens from private collections and auction catalogs are being made available in CRRO through the ANS' SITNAM database. Eventually, this will enhance the coverage in CRRO to some 300,000 Roman Republican coins.
