What are concordances?
A concordance is a cross-reference table that maps catalog numbers from one numismatic reference work to another. Ancient coins are cataloged under multiple systems — a single Roman Republican denarius might be cited as Sydenham 140, Crawford 44/5, Babelon Iulia 1, and BMCRR Rome 458.
Concordances are essential tools for collectors and scholars who encounter references in older literature and need to translate them to the current standard system, or who want to look up all known catalog numbers for a given coin type.
The tables here are derived from concordances published in the reference works themselves. Where possible, entries are linked to their corresponding type pages in the NumisLens catalog.
