Tanka - temp. Farrukhsiyar ibn Khalil Allah (1st Standard) - Shirvanshah dynasty

Dating from the period, the Tanka - temp. Farrukhsiyar ibn Khalil Allah (1st Standard) - Shirvanshah dynasty of Shirvanshah dynasty (Islamic Caucasia) (869–1472), denomination 1 Tanka, is a fascinating numismatic artifact. This coin from the era reflects a monetary world very different from our own. Struck in silver, this coin merges artistic merit with precious metal content. Silver's characteristic luster, when preserved, gives these coins a visual brilliance that base metal pieces cannot match. The natural toning that develops on silver over decades or centuries — ranging from golden-brown to deep iridescent hues — is prized by collectors and adds a layer of aesthetic complexity to these already appealing objects. For the serious numismatist, acquiring this coin in the finest available grade is the ideal strategy. Professional certification from NGC or PCGS not only authenticates the piece but encapsulates it in tamper-evident holders that protect against accidental handling damage. The long-term value proposition of well-graded, original-surface examples of numismatic rarities has been demonstrated repeatedly in the major auction houses of New York, London, and Hong Kong.
