Kazakhstan's currency -- the tenge -- was introduced 20 years ago, replacing the Soviet ruble in the newly independent country at a rate of 1 tenge to 500 rubles. The bold, innovative design of the banknotes has won the tenge a series of international awards. November 15 is marked each year as the Day of the National Currency of the Republic of Kazakhstan.
