The coin image dataset is a dataset of 60 classes of Roman Republican coins. Each class is represented by three coin images of the reverse side acquired at Coin Cabinet of the Museum of Fine Arts in Vienna, Austria.
The image filenames have the following syntax: class[classid]_image[1-3].png The dataset also contains a CSV-file “classes.csv” which maps the class-IDs to the reference numbers defined by Crawford’s standard reference book .
