I recently seen one similar to yours if not the same at a local auction LNIB go for $225 so I would guess if you listed it on GunBroker you could get close to that if not a bit more. If I was taking it in on trade I would give about $150 and put it out for $250 to see what happens. Generally the ones with engraved stocks bring about $50 to $75 more than the standard wood stock models on the used rack.
