I have a friend who wants to sell deceased brother's S&W Model 25-3 45LC Anniversary Model revolver with case and book. She asked me what the value is, and I have see a couple go for around $1200-1300. However, the silver/nickel medallion is missing from the case, and the insert has a small tear under the muzzle/front sight area. Otherwise the revolver is unfired and mint. I am guessing the value is ~$1100?, but tough to figure....any ideas?
