Probably not - but it isn't his decision, and the kids are not yet in a place in life where they can make the decision.
Until the kids figure out where their life will take them they can't know. I have some heirlooms that I'm really glad to have now, but when I was in college living in dorms I wouldn't have had space for them.
You have no clue what somebody else finds important and will throw the wrong things.
