2.1 g, copper, 21 mm (Quattrino size) Ob: "BENE XIV.P." with Papal Arms Rev: "ST VBAL EPISCOP." St. Usbaldus is the patron saint of Gubbio, I believe. There are several Gubbio undated quattrino types under Benedict XIV. I believe this one may be Gubbio, KM#127: Undated, 1745 Quattrino of Benedict XIV. Reverse is "St. Usbaldus, Standing, mitered, crosier right". A photo to compare would have been nice, but I'm reasonably confident in the ID. None of the other 1700s Papal States quattrini look close. Krause has if for $10 in VG, I got this one for $5.
