Depends on what grade the rifle is. Grade I, II or III? Grade I = Standard Grade, Grade II has engraved prarie dogs and squirrels, Grade III has dogs flushing some ducks and a dog with a duck in its mouth on the top of the receiver. You can tell what year the rifle is by the serial number.
Find out what grade it is, the check on Gunbroker what they have sold for. (not what they are asking)
