Watch List notes:

IRAN: Nasir al-Din Shah, 1848-1896, AE 50 dinars, Tehran, AH1281, KM-Pn3, bright original luster, cleaned, PCGS graded Unc details, RRR. This pattern was struck in the size actually 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: 800-1,000 USD
