Your wife and your kids and you heirs don't give a damn about your pre-64 Winchesters. Collectors are hoarders so they are never going to be able to part with them while they are still alive. Then the people left behind, who don't care a damn about them, send them to an auction house and pay 20% sales commission on them.

You want to collect guns? Fine. Call it what it is, a hobby or in some cases even an obsession. Don't rationalize it as an investment. You are doing your family a disservice.

You want to do the people you love a favor; leave them liquid assets.
