La zecca di Modena nei periodi comunale ed estense
A numismatic catalogue by Arsenio Crespellani, published in Modena in 1884, recording coins struck by the city's mint under communal and Este rule for collectors and local historians. Line engravings pair obverse and reverse as linked discs: armoured rulers, crowned profiles, enthroned Saint Geminianus, eagles with quartered shields, and circular Latin lettering usable as roundel and seal motifs.
