These Turkish people settled around Lake Van in North Eastern Turkey. They were known as "White Sheep Turkcomans" because of the black sheep emblem on their standard. In 1469 the White sheep Turcomans conquered another Turcoman tribe, the "White Sheep" Turcomans, and the two clans were united. Both these tribes issued their own coins to the Timurid standard (tanka of Shah Rukh of about 5.1 grams or sharukhi), all of which are fairly scarce and difficult to find.
