Pam,
It is a valuable gun. I would not recommend hanging it on the wall. I'll let the experts give you an appraisal. But, unless I'm out to lunch, it will be well up in the 4 figures. You might want to take a sharp picture of the bore so they can see the degree of pitting. Shine a light through the cylinder and barrel to the muzzle and shoot down the bore from the muzzle.

(I type too slow. I see I was thinking like Gary. Scary!)
