About $100 for trade in or sale to pawn shop or LGS. $300+/- depending on how good the sporterizing job has been done. As with all sporterized rifles that are unknown it is best to have them checked out by a good gunsmith. The VZ24 is a good action, and if all the work was done right a very serviceable rifle.
The scope is a BSA if memory serves me, just take it off and throw it at the target. You'll probably have better accuracy that way.
