1 Quadrupla - Paul V

Paul V — born Camillo Borghese — issued this quadrupla during one of the most politically turbulent pontificates of the seventeenth century. In 1606, just five years before this coin was struck, he placed the entire Republic of Venice under interdict following a dispute over clerical jurisdiction, the last time any pope successfully deployed that weapon against a major state. The standoff lasted over a year and ended in compromise rather than papal victory, a result that quietly signaled the diminishing temporal reach of Rome.

The quadrupla denomination itself was never a coin of ordinary commerce — these circulated among merchants, diplomats, and treasuries, not markets. At .986 fine, the gold content is exceptionally pure for the period.
