I have a Marlin model 39D that I received from my father as a gift for Christmas a few decades ago. I still have it in the original box with the owners manual, original price tag $69.00. It is still like new as I only snuck it out and shot it once. I also had a Winchester single shot and used it instead. My father thought it was safer for a youth to use a single shot. I understand the 39D was made only for a few years. Is there any collectibility to this rifle and estimates on value? I have 3 sons and am wondering about breaking it out for them to use or keeping it "as new in the box". I know if it were a Winchester 61 I would keep it in the box, but I am not up on the later Marlin .22 levers. Thanks for any wise advise from the Marlin experts that frequent this sight.
