Watch List notes:

IRAN: Nasir al-Din Shah, 1848-1896, AR shahi sefid, Tehran, AH1298, KM-889, a lovely bright white lustrous example! PCGS graded MS64. These 'shahi sefid' (white shahi) were intended mainly as 'nowruz' (new year) presents, so though they were only worth 150 dinars they were struck on broader and thinner planchets than the smallest other silver denomination, the quarter kran or 'robi' (250 dinars). This made for a slightly more impressive present at a lower cost.

Estimate: 75-100 USD
