I think my thing is the thrill of the hunt, be it marbles, Blenko, canes, knives, etc.
it started with my grandparents things, a small box of marbles, an old pocket knife…
we also like to buy low and sell high when the time comes. Our kids want nothing, except my guns which they aren’t getting. Those will go to our executor as payment for having to deal with our kids crap when the time comes.
