Explanation:

The manat is the currency of Turkmenistan. It was introduced on 1 November 1993, replacing the Russian ruble at a rate of 1 manat = 500 rubles. The ISO 4217 code was TMM, and the manat was subdivided into 100 tenge. The abbreviation m is sometimes used, e.g., 25 000 m is twenty-five thousand manat.
