Muraiola of 4 Bolognini - Clement XII Bust left

Clement XII — Lorenzo Corsini — was elected in 1730 at age 78, already partially blind and governing increasingly from his bed. The Bologna mint continued striking under his authority throughout his pontificate, though effective administration fell to Cardinal nephews and curial officials well before his death in 1740. The muraiola denomination itself was a product of Bologna's semi-autonomous monetary tradition, persisting long after similar billon fractions had been abandoned elsewhere in the Papal States.
