Zeri Mahbub - Mahmud I

The Zeri Mahbub was introduced under Mahmud I as a specifically Egyptian gold denomination, minted at Misr and calibrated to local commercial needs rather than conforming to standard Ottoman monetary weights. Egypt's position as a revenue-generating province meant its mint operated with considerable autonomy, producing types that rarely circulated far beyond the Nile valley and the Levantine trade routes feeding into it. The denomination name — roughly "beloved gold piece" — reflects the coin's intended appeal as much as its function.

KM#87 is among the earlier datable strikes of this type, predating the series reforms that would follow later in Mahmud I's long reign.
