There is a lot of room in that question. The mdl 39 was introduced in 1922 and has many variants manufactured up until at least 1988. Early model standard rifles in excellent condition can command $1500 and "Deluxe" examples can go to $2500. Through the '40's, the values go to $1200 and in the '50's to $400. A new in the box 1960 Presentation model goes for $1200 (unfired) and the 1970 Century Unlimited goes for $350. Most other examples go to about $300 or so. If you think it is an early model, take it to a gunsmith or advanced Marlin collector and pay for an appraisal.
