Papal coat of arms in a baroque cartouche, beneath a tiara resting on the keys of paradise in saltire., Saint Petronius standing frontally, wearing a mitre, holding a long crozier in his left hand and a miniature representation of the city of Bologna, recognisable by its towers, in his right hand. At his feet are the coat of arms of the Vice-Legate Monsignor D'Aquino and, on the left, the coat of arms of the city of Bologna., Certified by PCGS, but not encapsulated, with a recommendation for restoration. Graded PVC Residue. Very fine example with limited circulation damage, although there are a few traces in the fields, which have slightly damaged the grey patina.
