As a collector, I see folks all the time commenting on one side or the other about "values" of a firearm. It is your gun,, right now. But none of us are permanent owners of anything. If we get buried with any possessions, they will ruin away. We are all temporary owners.
None of us like to buy anything & see it's value diminish as a result of our negligence. Buy a new car & plan on using it off road immediately & scratching it all up, adding dents to it etc. Nope, very few folks do that. It's only after we've had it a while, and little stuff has affected it's finish, or value that we take a vehicle off road & not get too upset when we scratch it etc. It too me 10 years & a lot of miles, and a few other dents & scratches before my truck went deep off road & came home with a lot of brush scratches. I still feel badly when I look at it.
A firearm in pristine condition, can & will bring good money if & when it gets sold. If is up to you, the current owner. When is sometimes up to your heirs.
Go price a pristine 1960's Corvette. Look at what it sold for initially. Can we say "sticker shock?"
So, when a person discusses values of firearms, I often think; "If I keep my pristine collector grade guns in the same shape, one day, their increased value may help pay for much needed things for me." Health care, grandkids education, retirement funds, or whatever. So when I see minty guns get used, and worn, I know the value of my collectables has risen just a wee bit more. When I see "shooter grade" guns, I smile as well. I know they have already provided someone with pleasure in their use, and as such, I buy those as well,,, to shoot & enjoy.
But when I see a shooter grade gun that has been "restored," modified, or whatever, I look at what the seller is asking for it. Just last weekend, at a gun show, I saw a 4 digit Super Blackhawk for sale. The price? Asking $750.00. But, I saw the filed off front sight, the incorrect grips, (NM,) and the obvious re-blue,,, not the best, but "pretty." They didn't do a correct job, like rugerguy mentions, and it was obvious to me.
A nice 4 digit that was no longer collectable, OR worth what the seller was asking. To me, a shooter grade gun, that I personally wouldn't pay more than $400 for. Why? I might have to replace the barrel or at least the front sight & reblue the gun again. And I'd still just have a $500 shooter grade 4 digit OM Super. But, place a 4 digit Super in correct configuration, not reblued or whatever in anyway out for sale at $750 & I would have likely brought it home.
And on the flip side.
A rarer gun, of which is very desirable to many, in poor condition finish wise, will get passed over by collectors. But, take the same gun, have a PROPER reblue done, allow it to be shown as a reblue, will actually bring more value as it looks more like original & can be used to fill a hole in a collection until a better example is found. I have an early Standard Auto that was redone for me. It's finish was well worn & bad. But the gun was sound. I had a GOOD person do a PROPER job of rebluing it for me. Many folks would have a hard time seeing it as a reblued gun. But I never show it as anything but a reblue. But the value of it has increased,,, as it was properly restored.
So, listen to what rugerguy says,,, he's been there & done that.
