Uzbekistan

The sum is the official currency of Uzbekistan.
Uzbekistan replaced the ruble with the sum at par in on 16 July 1994. No subdivisions of this sum were issued and only banknotes were produced, in denominations of 1, 3, 5, 10, 25, 50, 100, 200, 500, 1,000, 5,000, and 10,000 sum. Because it was meant to be a transitional currency, the design was rather simplistic.
Etymology:
The word sum (alternatively transliterated “som” or “soum”) means “pure” in Kazakh, Kyrgyz, Uyghur and Uzbek, as well as in many other Turkic languages. The word implies “pure” silver or gold.
