The naxar (co-spelled nakhar or nahar) is the name of the currency that Chechen separatists planned for the Chechen Republic of Ichkeria.
In 1994, in the UK, banknotes were printed in 1, 3, 5, 10, 20, 50, 100, 500, and 1000 nahar denominations, dated 1995.
This currency was not put in circulation, and almost all printed banknotes stored in bank of Grozny were destroyed by the Russian military.
