The Kazakh central bank unveiled the new 20,000 Tenge note on Monday evening, saying it would become legal tender on Tuesday December 1, 2015. The largest denomination currently in circulation is 10,000 Tenge.
Kazakhstan's elaborately decorated bills are regular winners of banknote design awards. The new 20,000 tenge banknote, in an indigo hue, depicts on one side the Kazakh Eli monument to Kazakhstan's independence, and on the other Mr Nazarbayev's presidential palace.
