The Coin Hoards of the Roman Empire database currently contains more than 18,000 coin hoards from all areas of the Roman Empire and beyond. This large data collection encourages data-driven approaches to research the ancient world. However, there are several sources of bias in the data that make data-driven research difficult. One problem is that the hoards are recorded differently. For some hoards, archaeological information is available; for others, only numismatic; and for others, not even the exact location of the find is known. This paper uses logistic regression to analyse whether the data quality correlates with some observable hoard characteristics. It can be shown that numismatic data tends to be superior for hoards from the first century AD. In addition, there are significant differences in data quality between hoards from ancient cities and forts versus those in rural areas or outside the Roman provinces.
