What it's worth may be affected by the area in which you live. It's a pre-64, in a caliber that was once kind of overlooked, but these days seems to be kind of rediscovered by many, especially the cast-bullet crowd. If someone wants to sell it to you for $150, and it's in decent shape, whip out your cash, credit card, or checkbook and scarf it up. There's people out there that are paying over $400 for these, in decent shape. While a Marlin 22 levergun is nice (or used to be before Marlin went under), you could be looking at a good deer rifle here, not to mention a collector's item, at $150.00.
