here, where you can also find links to view the scans. The creation of RRDP, a die study for the entirety of Roman Republic coinage, is a Herculean effort that Schaefer has spent decades on, and its digitization likewise something that many people at the ANS have put a great deal of time and money towards for the past few years. This archive will, without a doubt, be of the utmost importance for future studies of Roman Republic coins, and even before it was digitized I know that many papers over the past couple of decades in Roman Republic numismatics benefited from it, as many researchers would write Richard requesting scans as the first step of any new research. I highly recommend taking a look, even if you're not into Roman Republic coins, because there's a lot you can learn about how one might undertake a die study. RRDP is a great example, for instance, of how even an ugly, worn coin is just as important as a beautiful FDC example when it comes to a die study. The way that the coins are divided up for die classification(e.g. based on slight differences in position of one element or slight stylistic differences) is a great model for how to break down an issue that might have hundreds of dies into smaller, more manageable chunks that can be studied.
