Circulation coins were first introduced in January 2008, making Kyrgyzstan second to last of the former Soviet republics to issue them.
Belarus became the last.
  This move came with growing demand from vendors for coins, especially from slot machine industries and those desiring a more efficient system for collecting fare money.

The coins were issued in denominations of 10 and 50 tiyin and 1, 3 and 5 som.
A 10 som coin was issued a year later for 2009.
 
All coins are minted by the Kazakhstan mint in Ust-Kamenogorsk and bear some resemblance to coins of the Russian Federation.
