I just sold a Colt Trooper MK III .22lr no box for $525. The magnum version is more rare, so, obviously worth more. I also just sold a Colt Detective Special for $325. Earlier this year I sold a nickel Colt Cobra in the box for $465. And. last, but not least, I sold a nickel S&W model 19-4 with the box for $375.
I recovered what I paid for the guns, which is better than I normally do, but I kept hearing and reading how these guns were worth "this much" or "that much". So, after several months of trying to sell these guns for "this much" or "that much" I took what people were willing to pay.
