Mahmud I Kurush

The tughra on the Mahmud I Kurush, that elaborate calligraphic signature of the sultan, often varied slightly with each minting, reflecting the empire's decentralized production. It's a subtle nod to Ottoman bureaucracy, where even coins had to bow to regional differences.

Struck from silver of varying purity, typically around 0.500 fine, these kuruş circulated as the standard currency during Mahmud I's reign. We know they were produced in multiple mints, including Istanbul, but exact outputs remain uncertain—many records burned in later conflicts.

One version featured a reverse inscription citing the Islamic creed, a common touch that didn't always prevent counterfeits. I've handled hundreds; they wear down quickly in use, like most things in life.
