BillyJack,
You have to be careful of the terms that you use to describe your used firearm. In the gun collecting world, the term "good condition" actually means a gun that is really beat up. The stages of condition above "good" are very good, fine, excellent, and mint.
Most folks describe the condition of a collection piece by the percentage of original bluing still on the gun overall. (Such as 90%, 95%, 98%).
After the percentage of bluing is expressed, it is expected that the firearm as a whole (action, barrel and stock) be in a condition that is consistent with the use normally associated with the amount of bluing that is worn off. In other words, that the gun has been used, but not abused, and has been well maintained, with no rust, large scratches, chips, damaged bore, etc. If these are present, then the value of the gun is significantly reduced.
Just some info.
