SuperCub, you've just gotten older, narrowed your interests beyond the common stuff, and moved on to enjoy the "special" stuff, near and dear to you.
You may also be considering what would happen with the "other stuff" should something go severely awry at this point in your life and whether your heirs would have a clue what they have in front of them or know how to get the type of value out of them you would be able to.
Not that many years ago, I had close to 900 firearms. They're mostly gone now; some very nice specimens were "paid forward" to people who appreciated them for what they were. Most were sold to pursue other interests.
I still have several firearms I find interesting or have issues parting with.
My wife has zero interest in firearms and looks at some of them, thinking, "I could go to Hawaii with the proceeds from that."
The trouble is, she hasn't got a clue about moving them on or even where to start.
My stepson loves everything that goes bang, hopefully with plastic stock.
He might sell them for her, but at ridiculously low prices because he has no idea about their value.
So, the time came a few years ago for me to narrow my interest range and move things along to others to take care of for the future.
I've had a lot of fun along the way and used firearms for stressful life conditions, as well as having fun and harvesting game.
Now, I'm enjoying going to shows, moving some of the stuff, a bit at a time.
I'm choosey though, if I don't like the potential buyer, it isn't going to happen under any circumstances.
There should be more of that going on. People need to be pickier about "who" they sell a firearm to.
Go well on your new path, not all of the value is in the cash those firearms will bring. More in the real enjoyment they will bring.
Once you've done the bell curve, where do you go from there? Sort of like letting your home-made wine "cure" for six months to a point it's barely palatable or letting it "age" for ten years before opening.
