Moving to NV where I don’t know anyone and having friends that are as old or older than I am I had to think about this for everything recently.
My audio gear, records and CDs go to my local audio repair shop. He appreciates and repairs the old hardware.
My guns go to my favorite gun store.
My jewelry and precious metals go to a friend.
My hobby collection goes to a computer museum.
Everything else gets sold for cash and joins the bulk of my estate. Which is then distributed to museums and animal rescue organizations.
