The Imperial Seal of the Mongols is a seal (tamgha) that was used by the Mongols. The imperial seals, bearing inscriptions in Mongolian script or other scripts, were used in the Mongol Empire, the Yuan dynasty, and the Northern Yuan dynasty, among others.
According to Plano Carpini, the Russian handicraftsman, Kozma, made a seal for Güyük Khan. This seal might have been a seal used to stamp the letter to Pope Innocent IV.
