New Data Release from the RRDP Project

by Alice Sharpless and Lucia Carbone

This blog post accompanies the second release of data for the RRDP Project. You can read more about the project and the first release in Carbone and Yarrow’s July 13, 2021 blog post.

With our second data release we are continuing with our focus on the period of 92–75 BCE (RRC types 336–392). The new release includes the following RRC types:

Some of the issues released, i.e., 357/1a, 357/1b, and 385/4 are ODEC: One Die for Each Control Mark (Fig. 2).

Figure 2. RRC 357/1b, ANS 1941.131.162.

As the name suggests, ODEC issues have a specific correspondence between dies and control marks. Usually there is a univocal correspondence between obverse and reverse dies for each of these control marks. Early on, Schaefer realized the value of these types for understanding the coin production processes used at the Roman mint and also for testing and improving statistical models for estimating the original number of dies used to strike an issue. The current release has allowed us to add a total of 3,515 specimens to CRRO, including 2,541 ODEC specimens, thus further enhancing our knowledge of ODEC issues.

Figure 3. Schaefer RRC 344/3 Reverse 67 featuring new control symbol.

344/3 was minted under L. Titurius Sabinus in 89 BCE (Fig. 3). Crawford counted 200 reverse dies, but with Schaefer’s materials this number has been raised to 224. Schaefer’s materials also reveal six new control symbols of Titurius Sabinus:

Schaefer’s materials also include a second example of a variant reverse die where Victory holds a whip rather than wreath, with no control mark. Crawford had already noted the example in the collection of the University of Oslo. Before this data release there were 283 specimens represented in CRRO. There are now 770 specimens in CRRO.

Figure 4. RRC 385/4, Peacock control mark.

357/1a and 357/1b both date to 83 BCE, minted under G. Norbanus. 357/1a seems to be a small issue. Schaefer’s materials provide examples of 26 obverse dies. Crawford gave a range of numbered control marks from I to XXVI. Schaefer’s materials also include specimens with the control marks CXXXXVII and CXV (one die for each). These higher control marks might indicate that the issue was much larger than previously known, or these may be imitations. Before this data release there were 49 specimens represented in CRRO. There are now 217. 357/1b is a much larger issue. Crawford noted 156 obverse dies, but we can now raise that number to 210,with an additional 5 imitation dies. These materials do not add any new control marks to the range of I to CCXXVIIII provided by Crawford. Schaefer’s materials also show that this particular issue has a high number of brockages. This data release has added an additional 1,796 specimens to CRRO.

385/4 is another large issue minted under M. Voltei M. F. in 78 BCE which has both obverse and reverse control marks. This moneyer created a series wherein each of the five coins celebrates a different major religious festival: the ludi Romani (or plebeii, represented in RRC 385/1), Cereales (RRC 385/3), Megalenses (RRC 385/4), Apollinares (RRC 385/5), and, as it is suggested by the types on RRC 385/2,  the short-lived ludi Herculani (for a criticism to this chronology, see Keaveney 2005).The issue included in this data release thus celebrated the ludi Megalenses, which were established in 204 BCE to honor the Magna Mater, Cybele, as suggested by the reverse. Schaefer’s materials reveal 78 obverse dies (an increase from 71 noted by Crawford), although one is likely an imitation. There are 79 reverse dies (an increase from 71 noted by Crawford), three of which are probably imitations. This RRDP release has increased the specimens on CRRO from 182 to 759. Most notably, Schaefer’s materials also contribute six new obverse control marks that were not included by Crawford. They also allow for four corrections to Crawfords list (see table). Schaefer has shown that two of the reverse control marks (ΛΕ and ΜΘ) actually have two associated dies though there is no corresponding change in obverse die. This may suggest the original reverse dies broke or were damaged earlier than expected. The following table shows the updated list of control marks. New or corrected control marks are in bold. Schaefer also includes one specimen which appears to be an imitation of the Thyrsus/Θ pair. We are indebted to our volunteer David van Dyke for his work on this issue.

A second group of issues included in this release is instrumental in illustrating the financing of Sulla’s campaign in Italy in 84-82 BCE. 359/1 (aureus) and 359/2 (denarius) are issues of L. Cornelius Sulla. For 359/1, Schaefer’s materials add five new specimens to CRRO, with the result that CRRO now includes all ten known specimens. Crawford recorded 6 obverse and 6 reverse dies for 359/1. Schaefer’s materials reveal another two for each, for a total of 8 reverse and 8 obverse dies. For 359/2, Schaefer’s materials provide 187 reverse dies—a significant increase from the 36 reverse dies Crawford recorded—and add 277 specimens to CRRO. There is a high number of singleton reverse dies, an element that could hint at an Eastern mint for these issues. An Eastern production is also suggested by the die-axis, which present a strong tendency toward 12:00, a common practice for Greek coinage, but almost unattested in Roman Republican coinage The Eastern minting techniques, together with the iconographical similarities between the reverse of these RRC issues and the so-called Athenian ‘trophies’ tetradrachms, strongly connect  RRC 359 issues to the early phases of Sulla’s reconquest of Italy (Figs. 8–9). 

Figure 8. Reverse of RRC 359/2, Berlin MünzKabinett 18206086.

The anonymous issues 375/1 (aureus) and 375/2 (denarius, Fig. 1) were recently published by Alberto Campana (“L’Emissione con “Q” di Silla (RRC 375/1–2, 82 a.C.)” Monete Antiche 118 (2021): 3–30). The aureus 357/1 is known from only a single specimen in the BnF (REP-21376). For 357/2, Campana includes more specimens than Schaefer and identifies 40 obverse and 111 reverse dies plus two plated obverse and reverse dies. Schaefer’s materials include 98 reverse dies and add 205 specimens to CRRO. On the basis of hoard evidence, Campana convincingly argues that these issues should also be included among the ones financing Sulla’s campaigns and possibly dated to the same years as RRC 359 issues. The contribution of RRDP to our knowledge of Sullan campaign financing strategies will be presented by Lucia Carbone on November 10 at the University of Virginia.

The next RRDP release, tentatively scheduled for January 2022, will include all of the RRC 367 types, also related to the Sullan campaigns of 84–82 BCE. Crawford identifies five types (three denarii, two aurei) of this joint issue of Sulla and L. Manlius Torquatus. But it seems this issue can actually be broken down into more than five types, some of which were marked with control symbols. By focusing on 367 we aim to disentangle and revise Crawford’s typologies.

Binders of Richard Schaefer’s Roman Republican Die Project (RRDP) now online

The practical problem is that counting all the dies used to strike during the Republic would be the work of several lifetimes.

—M. H. Crawford, Roman Republican Coinage, 641

In 1974 M. H. Crawford authoritatively stated the virtual impracticability of comprehensive die studies encompassing the whole Roman Republican monetary production.  For this very reason, he turned to estimating monetary production through hoard studies (e.g., RRC Tables L–LVII). This method was further developed by, among others, Kris Lockyear, who further expanded Crawford’s archive of Roman Republican hoards, produced a landmark statistical study on the patterns of monetary production based on these data, and continues to use the data to improve our understanding of the relative chronology of the series.

However, about 25 years, ago Richard Schaefer began to collect systematically images of all struck Roman Republican issues included in Crawford’s Roman Republican Coinage.  While no precise final count is available yet, it is estimated that Schaefer has documented and analyzed some 300,000 specimens in the Roman Republican Die Project (RRDP). His archive thus proves that it is indeed possible, even if extremely challenging, to create reliable quantitative data for the monetary production of the Roman Republic. Schaefer’s study encompasses all struck Roman Republican issues included in Crawford’s Roman Republican Coinage with a few logical exceptions, like the large issue of C. Piso L.f. Frugi (RRC 408, c. 61 BCE redated based on the Mesagne hoard) for which Charles Hersh had already produced a complete die study. For each issue of struck coins, Schaefer determined the die links for either obverse or reverse.  The goal of this project has been to collect enough images and identify enough dies to achieve 90% or better coverage. Fig. 1

Schaefer’s notations on each clipping record the image source, as well as any and all information in the source such as weight, axis, diameter, and his assigned die identifier (a number or a letter). The specifics of Schaefer’s collecting and analysis methods are detailed in our article for the ANS Magazine “Opening access to Roman Republican Dies”. Schaefer’s archive consists of 14 three-inch three-ring binders. Fig. 2

These hold at minimum the two best examples of all known dies for all issues covered by RRDP and on occasion additional specimens.  Of course, the binder only has one example in cases where a die is only known (so far!) from a single coin.  Further examples of the known dies represented in the binders are stored in die order in small drawers (“output” or “output clippings” in the evolving language of RRDP) , each of which can hold up to four hundred images. These clippings should join the binders online by the end of summer.  Fig. 3

The same type of drawers and the same organization is used to store a special sub-set of thirty-five types of particular interest to those interested in the statistical analysis and quantification of surviving dies versus the original number of dies.  These types make up a collection called ODEC for short (One Die for Every Control-Mark). As Schaefer says, around 2000 he “realized the ODEC issues could tell us how many dies we know out of the original total; inversely, they tell us how many dies we still have not found.  For example, if an ODEC issue has control numbers 1 to 150, the missing numbers give us the number of dies still not found.” Readers familiar with the importance of Theodore ‘Ted’ Buttrey study of the P. Crepusius denarii will already be acquainted with this type of evidence and how it has taken center stage in debates over quantification.  ODEC only includes issues that are large enough to be statistically meaningful; thus it excludes the smaller issues which are treated in the binders as ordinary types (RRC 376, 398 and 399) and issues like RRC 350A/3 which is huge but the control letter is too often off the flan and thus the current number of specimens in RRDP is statistically too small. Schaefer has also documented that not all of thirty-five types considered to have only one control mark per die by Crawford actually fit that description; of these, quinarii issued by a P. (Vettius?) Sabinus in c. 99 BCE (RRC 331) have by far the most symbols repeated on different dies.  Another curiosity that Schaefer discovered is the issue of serrated denarii by C. Naevius Balbus (c. 79 BCE, RRC 382); control numbers 1–39 are all represented by two or more dies, but almost all numbers 40–226 are represented by only one die.  Schaefer’s work on ODEC will prove invaluable for testing and verifying new and existing statistical models for quantification. Fig. 4 The ODEC images will be made public at the same time as other clippings.

In early 2019 the ANS partnered with Schaefer in the Roman Republican Die Project, aiming at making available to the public what is likely to be the largest die study ever undertaken.  The first part of this project consisted of the digital preservation of Schaefer’s archive and was completed in June 2019. In this initial digitization phase, we aimed to publish the binders and the clippings, assembled as TEI files of facsimile images, published the ANS archival platform, Archer and linked to CRRO. Fig. 5. The binders, the largest part of Schaefer’s archive, are now online and available to the academic community.  We aim to have all further images accessible by the end of the summer.

The second phase of this project consists in the quantification of Schaefer’s die counts as recorded in these images. The whole process entails the creation of spreadsheets for each RRC type, including a listing of each obverse and reverse die, and a number of occurrences for each die. Eventually this statistical data will be published and made accessible through Coinage of the Roman Republic Online.

We envision a much more ambitious third phase after all the existing data is publicly available in which we create a research group and digital tools to expand on Schaefer’s work, incorporating new specimens and increasing coverage of all issues.

The die studies realized by Richard Schaefer and now digitized and organized in ANS Roman Republican Die Project (RRDP) are an invaluable asset to the study of Roman Republican History. They could prove instrumental to show A) the accuracy of the figures provided by ancient sources and B) the reliability (or not) of Crawford (and later) production estimates based on hoard counts.

Ready to see the Schaefer’s binders for yourself?  There are multiple ways into the material:

If you want to view the whole binders just as they are on Schaefer’s office, you can flip through each binder and zoom in and out directly in Archer, the ANS archival platform.  Below the page viewer, you will find an index of the binder organized by RRC number that allows you to jump to a specific type in that binder.
