Altmislik - Abdülhamid I Kostantiniyye mint

The altmislik — a 60-para piece — was introduced as part of Abdülhamid I's monetary reforms following the financially catastrophic outcome of the Russo-Turkish War of 1768–1774, which ended with the Treaty of Küçük Kaynarca forcing the Ottomans into substantial reparation payments. The billon content of these pieces reflects a treasury under sustained pressure; the silver fraction had been quietly degraded across successive issues throughout the latter eighteenth century.

Kostantiniyye production during this reign is reasonably documented, but die alignment and flan preparation were inconsistent enough that well-centered strikes are genuinely harder to find than the survival rate would suggest.
