Imam Ghalib ibn Ali gold "Secretary Bird" Proof 200 Ryals AH 1391 / 1971 PR64 Ultra Cameo NGC, KM-Unl, Fr-2. According to Gold Coins of the World, this is a rebel issue, and the mintage must have been quite small, as we've sold no other examples and none appear in a search of archived auction results. This example, despite showing light handling, presents rather nicely, with a rich cameo appearance that reflects high quality manufacturing. Two small as-made privy marks are noted near the border behind the eagle and bird design.
