Value is very subjective. Why? Condition, as well as having the complete package comes into play. By complete package I mean all the paperwork that was in the box when new, as well as the box, AND the shipping carton. You mention a little rubbing on the barrel. And you have shot it,,, so the gun is not new. This falls to the condition. A PROPER grading is necessary to get a true value of any gun. You may think it's 98% while the actual NRA grading system may only give it a 90%. And with the fact that the age of the gun should allow for it to have all the packaging & such,,, the value could be from $500 to $900,,,,,,,,,, but it ALL depends upon many details.
We will gladly assist you in grading the gun, and giving an honest value,,, IF we know the details. Close up pictures,, details of any condition factors, all are needed to give a true value. If you will communicate with Hawkeye#28,,, I KNOW he can help & give you an HONEST value of it.
