I was talking to a book dealer the other day (I collect books, among other things) and he couldn't get past collectors who don't dispose of the collection before they die. I had to remind him that a lot of us don't collect things for the monetary value, but for the joy owning these objects gives us. And that getting rid of these things in a (to us) untimely manner was anathema to the whole enjoyment of collecting. When my father passed, his wife called her church, and they came and took everything as a donation. It was her business at that point, and this made her happy, When my FIL passed, my wife, as an only child, went and got his cats, we took the few things that mattered to us, and called an estate sale company.
All my stuff goes to my wife, and then my son. They both know how to deal with it; either keep it, or call an estate company. Seriously, not going to worry more than that.
