Coin Types

Ethan Gruber edited this page Sep 2, 2016 · 1 revision

Coin typologies are composed of a variety of characteristics: denomination, ruler or magistrates responsible for issuing, issue dates, mint, and the inscriptions, iconography, and other symbols on the front and back of coins. Types are uniquely numbered and published in printed volumes. We are beginning to restructure these printed data into XML and Linked Open Data on the web. So far, three corpora have been published online.

Roman Republican Coinage (RRC)

The standard work for Roman Republican Coinage is the eponymous 1974 publication by Michael Crawford. This has been published in a joint ANS-British Museum project, Coinage of the Roman Republic Online. The numbers often appear in print with the RRC appreviation, e.g., RRC 51/1. Types might be referred to by 'Crawford numbers' as well, e.g., Crawford 51/1 or 51.1. The URI sequence is established by replacing the forward slash with a period and appending to the rrc-prefix: http://numismatics.org/crro/id/rrc-51.1. You will not encounter RRC numbers in ebooks before 1974.

Roman Imperial Coinage (RIC)

Roman Imperial Coinage (RIC) is a 10 volume work of more than 40,000 coin types issued by the Roman Empire from Augustus to Zeno (27 B.C. - ca. A.D. 500). Most of these volumes were published over the first half of the 20th century, but some volumes have been revised and reissued (such as the first volume, from Augustus to the three emperors that follow Nero). You might encounter RIC references in mid-century publications. RIC numbers that refer to the early empire (Augustus and the Julio-Claudian dynasty) likely refer to the first edition of RIC Volume 1. RIC Volume 1, second edition has been published in Online Coins of the Roman Empire, so if you encounter these numbers, please let me know, as we have not created a concordance between the numbers in the first and second editions of Volume 1.

RIC is a little more complicated than RRC in that the numbering system resets over each emperor, whereas RRC's numbering is sequential throughout the book. Therefore, you will have to evaluate the context a bit further to determine which emperor referred to when you encounter a reference like "RIC 100". It is fairly easy to find the correct URI for a given RIC reference.

How to Search

  1. Go to the OCRE browse page
  2. Select the emperor from the "Authority" facet
  3. Enter the type number into the text input below the facets. You can use a '' wildcard, e.g., 100 will find 100A, 100B, etc.

URI Examples

The structure of OCRE IDs includes the volume number, the authority (ruler) abbreviation, and the unique number in the printed volume, concatenated with periods.

Price - Coinage of Alexander the Great

Martin Price published a typology of the coins of Alexander the Great in 1991, which was published online in 2015 in PELLA. I don't believe that these numbers will show up in this run of ebooks due to the recent date of this publication. But they are referred to by Price numbers, e.g., Price 4.
