INDIA. Sultans of Delhi. Tanka, AH 721 (1321/2). Delhi Mint. Ghiyath al-din Tughluq. NGC MS-61. CIS-D301. Soft yellow in appearance and with a very well centered and well executed strike, this enchanting specimen dazzles with a great deal of gleaming luster remaining. Undoubtedly a cut above that which is normally encountered.
