Kazakhstan is a landlocked country in Central Asia bordering Russia, China, and Uzbekistan. It has a population of 21 million stretched out over a very large territory which makes Kazakhstan one of the most sparsely populated countries in the world.

The Kazakh steppes were mostly populated by nomadic tribes. Genghis Khan conquered the area for the Mongol Empire in the 13th century. In later centuries Kazakhstan was loosely organised by Turkic tribes. Russian expansion to the east reached Kazakhstan from the 18th century.
Kazakhstan became an independent country after the breakup of the Soviet Union in 1991. Since 1989 Nursultan Nazerbayev has been the undisputed leader of the country. Kazakhstan's economy is mainly based on oil and mining, and after more than a decade of growth and rapid development now suffers from the recent fall in commodity prices.

Kazakhstan's national currency is the Tenge, derived from the silver Tenga that was used in Central Asia until the early 20th century. The Tenge was introduced in 1993 to replace the Ruble at 500 Rubles per Tenge. The currency was weak in the 1990's but pretty stable in the decade after at a rate of around 130/$. However, the recent collapse in commodity prices have caused the Tenge to devaluate 30% in 2015. There are now around 250 Tenge/$
The first series dates from 1993 with coins from 1 Tiyin to 20 Tenge. In 1998 a new series was introduced with coins from 1 to 50 Tenge with a 100 Tenge added in 2002. Kazakh coins are quite easy to find, but the larger denominations of 1993 are a bit harder to find.
