Personally, I have no use for wall hanging guns that still function, it's kind of like getting sent to the old folks home when you're 30, the gun isn't so old that it's unsafe to use, so use it. I also have no use for gold plated, fancy pants guns that were never meant to be shot, kind of like a beautiful woman that never gets glammed up and just wears sweatpants all day.

If you've been hunting the gun, keep hunting it, what's the odds you'd sell it even if it were worth as much as people might claim it's worth? My brother in law has a Pre-64 Winchester featherweight M-70 .270win, it's been appraised at just over $3k, and he's been offered $4500 for it and $5000 if the scope went with it, he hunts deer with it every winter, coyotes with it all summer, and shoots targets with it year round, it's still in pristene condition so the value is still good, but what would be the point of anyone having a gun just to look at.
