Watch List notes:

IRAN: Nasir al-Din Shah, 1848-1896, AE 50 dinars, Tehran, AH1281, KM-Pn3, pattern type, NGC graded AU58 BN. WINGS. This pattern was struck on the flan size later used for the 100 dinars denomination when that type was adopted for use in AH1297. The 50 dinars circulating coin, half the size of this piece, was first issued in AH1293. Although the mint name appears as Tehran on this type, it was likely struck in Belgium.

Estimate: 2,500-3,000 USD
