20 Lira Ahi Evran

Ahi Evran — full name Şeyh Nasîrüddîn Mahmûd el-Hoyî — was a 13th-century Anatolian scholar and craftsman who founded the Akhism movement, a guild-based brotherhood that structured artisan and merchant life across medieval Anatolia for centuries. The Turkish mint has issued a recurring series of commemoratives honoring figures central to Anatolian cultural history, and Ahi Evran appears in that lineup partly due to renewed institutional interest in Akhism's cooperative ethics as a pre-modern Turkish social model. His actual birth year remains disputed among historians, placing it somewhere between 1171 and 1205.
