| Reverse description | Within a beaded inner circle, a pair of spread bat wings is depicted in low relief, serving as the dynastic heraldic emblem of the Sforza family. The wings are rendered in a flat, stylised manner typical of hammered billon coinage of the period. A Latin circular legend in the outer margin reads CONSTANTIVS SF, identifying the issuer as Costanzo Sforza, Lord of Pesaro. The legend is introduced by a cross pattée and punctuated by pellet stops. |

| Additional information |
Costanzo Sforza ruled Pesaro as a condottiere lord — his authority rested on military contract as much as dynastic right. The quattrino was the workhorse of small transactions in the Marche, and Pesaro's billon issues of this period circulated alongside a chaotic mix of papal, Montefeltro, and Malatesta coinages in neighboring territories. Costanzo died in 1483 without a legitimate heir, and Pesaro passed to his illegitimate son Galeazzo, a succession that required direct papal intervention to legitimize.
