Issued as part of Turkey's ongoing commemorative program honoring figures from the broader Islamic intellectual tradition, this piece marks the 915th anniversary of Khayyam's death — a poet and mathematician born in Nishapur, in what is now northeastern Iran, who wrote the Rubaiyat and made significant contributions to algebraic geometry and calendar reform under the Seljuk Sultan Malik Shah. The enamel application on silver commemoratives from Darphane has been inconsistent across recent issues, with color pooling and edge bleed noted on several pieces in this program.
