Value of ANY gun is based on exact make, model, and condition. A well worn Yugo SKS may be $150, while a pristine Russian SKS is $500. An average Chinese SKS is around $250-$275.
The SKS isn't an assault rifle, although some of the Chinese variations (such as the SKS-M and SKS-D) do meet the criteria for the definition of a "civilian assault weapon" by BATFE regulations. Although China was prohibited from further arms sales in the US in 1994, the Type 56 carbine (Chinese designation for the SKS) is still pretty widespread, and can still be found at gun shops, gun shows, pawn shops, online gun auction sites, etc.
Depends on where you live.
