Howdy all! I'm hoping that I can get some constructive advice on how to go about selling my 1922 Colt .22 LR Police Positive Target (double action with rubber grips). It's been in the family for decades, and I know my kids have no interest in it, so I thought I'd sell it after seeing on the Internet that they sell for around $700. The only thing is, I don't know how to grade it (for condition), and where the best place to advertise it might be. It is in perfect working order and the bluing is a bit faded near the mussel end, but it is otherwise in very good condition. Any advice would be greatly appreciated. Thank you!
