Welcome to the Forum. There's a couple of factors involved here, that will affect the value. The box seems to have had more waer than the gun. If the box is original to the gun, meaning that's the box the gun was in when it left S&W, I would do some restoration on it to achieve the best price. Assuming the gun has not been refinish, and is truly 100% unfired, value, in the original box is $900 to $1,000. If the box is not original to the gun ( check for a serial number written on the bottom in pencil or crayon ) the gun is a $550 - $700 gun and the box is $100, or thereabouts.
