I'm going to take a different view of this for people to consider:

My dad collected a lot of stuff. He wasn't a hoarder because most of the stuff had value, but he had so many collections: Coins, stamps, cigarette cards, movie posters, movie memorabilia, LPs, CDs, DVDs, so many other things.

When he died, I had to deal with it. All of it. And I am not a material goods sort of person overall, so I didn't want most of it. It took me years to sell off what I could. We couldn't even sell off most of the DVDs, LPs and CDs. They ended up either given to friends or to thrift stores. I'm still dealing with it even though he died in 2016. Who wants a life-sized ceramic bust of Charlie Chaplin (dog for scale)?

Did I make money from selling it off? Absolutely. It even helped when we needed some money. But it really wasn't worth the near-decade of stress I've had to go through to deal with this stuff and there really is no end in sight.

And now my mom is in her 80s and she has a house full of antique furniture like this which, again, I have no interest in (and no room for at this point).

Do not make your kids deal with this stuff unless they really want to. I said I would deal with it because my mom is just not good at this stuff and my brother lives too far away, but if I would do it again, I would either hire someone to deal with it all for a percentage and wash my hands of the whole thing or tell my dad that he needs to sell it off before he dies.

Instead of having a few items from my dad to really treasure, I ended up with a bunch of shit I didn't want to deal with and it makes the stuff I do want to keep, most of which wouldn't be worth a huge amount anyway, have much less sentimental value to me.
