I have a 39A also and have always been fond of it. Great shooter. As for its worth, that depends on the buyer. I was an oil trader for a decade and learned some interesting lessons. Let's just say that the rifle is worth $300. Dozens of people would pay you $200 or $250. A considerable number would pay you the $300. A smaller number would pay $350. From this progression, you can see where I'm going. There will be somebody somewhere that will, for a reason known only to him, pay you far too much for the rifle. It's your job as the seller to find that person and give him the chance to pay too much. As for what the top number is, I have no idea. I'd start with asking for a price equal to replacement cost, if it's in real good shape, and go from there. Your advantage is that the rifle was made at a time of great workmanship by Marlin and it has no crossbolt safety. And...the more potential buyers you can find, the better your chances of getting top price. Negotiation is an art, and not just everyone can do it well. I should also mention that you should consider the options of the potential buyer. What is the cost of a new one and what could he pay for a used one from someone else? That'll tell you about what your sale range is.
