Without pictures or gun in hand, it is difficult to determine value. I have a 25-35 rifle also and am going to use it on deer this year. love the caliber.
if it is rough enough that it is not salvageable, it may be interesting to someone as a wall hanger...$ 100 if that, in very decent shape, it can bring into the 4 digit figures. Quite a desirable caliber as not many are still around. Very hard to find ammo so I reload for mine.
