Coin Hoards of the Roman Republic Online (CHRR Online) is a database of Roman Republican coin hoards mainly from the period 155 BC to AD 2. This database began life as a personal research database constructed by Kris Lockyear using a combination of published data and Michael Crawford's personal archive now housed in the British Museum. The online database, which utilises the Numishare application developed by Ethan Gruber, is a joint project between Kris Lockyear (Institute of Archaeology, University College London) and the American Numismatic Society. Project coordination provided by Rick Witschonke of the ANS.
