Inheriting Your Parents' Mid-Century Stuff

Why not direct them to these posts so they get the gist of your 'dilemma'. Can't do anything but good... May become a very popular thread.

Why not donate the best...
Why not donate the best pieces to the state gallery and/or museum?
They will take care of the pieces and everybody will be able to enjoy them.
Perhaps divide the rest amongst the kids. At the end of the day it is the memory of your parent that you hold close to your heart, not a chair.

Drive them to drink
by devising a complicated lottery system!

simple

DON'T divide it equally. The one who is jazzed about it should get it. Find another way of compensation for the other 2
They are great things because they are great, and the kid who thinks they are great will get the greatest kick out of them. It's not like dividing your liquid assets.

adopt me?
I don't need braces and have already paid off my college debt.

I would not donate it it to...
I would not donate it it to a museum unless I knew they would keep it.Otherwise they will sell it and use proceeds on whatever they so choose.
Could just do that yourself and help your own instead.
My father has always kept a tally of whatever he has given us siblings over the years and kept it equal.All birthdays,xmas always exactly the same too which is just cash.
I have heard many times of people who have worked their backsides off to make a normal life and buy a home and then the old parents feel sorry for the bludging,lazy son who does not own a house and wants to give it all to him.Poor boy it's not his fault.
This is extremely insulting at the son or daughter who did and become the good hard working human you taught for so many years.Best way to lose the respect of you kids in one fell swoop who did the right thing by you and themselves.The bludging child would only think you a sucker.Even if not being mean it's just human nature.
Give it to the one who loves it for what it is and not what it's worth.
The others get a cheque and only for the equivalent trade or Ebay value of the pieces at low estimate and less 10% selling costs.

The cumulative burden of possessions.
Sometimes I wonder if I'd be doing my kids a favor if someday I decided to toss a lit match over my shoulder on my way out the door in the morning.

I guess
it depends on if you left the kids inside...

Succinct, OGD. I like that.
Perhaps we should display similar restraint more often?

That's usually me...
Until I think someone needs help, then I go all out. I guess that was just the way I was raised. Sometimes though, it seems trying to be too helpful, isn't helpful. Even after a big fight or something, I'm over it quick, and on to the next joke.
I like the old George Burns type one liners.
He was talking about retiring once. He said he had a friend that retired 5 times in his life. He was convicted...
