Mangir Mehmed II

Mehmed II introduced the mangir as the Ottoman copper denomination following the conquest of Constantinople in 1453, establishing a trimetallic system — gold sultani, silver akçe, copper mangir — that would define Ottoman monetary organization for generations. This 1457 issue falls within the earliest years of that reformed coinage, when the new imperial monetary framework was still being consolidated across freshly absorbed Anatolian and Balkan mints.

Copper coinage of this period was struck at multiple provincial mints with little uniformity in weight or fabric, which accounts for the considerable variation collectors encounter across examples nominally sharing the same type.
