It's an interesting question which I think also relates to the memorabilia side as well.

Would I trade all my stuff for a signed Lou Gehrig jersey he wore in 1927? UMMM let me think...Heck Yeah!
I like being able to look at all my stuff, but most of it I could collect again and have the thrill of the hunt all over again.

I, like many others have mentioned, am also attached to many things in my collection because of memories of my father and our journey together through collecting. Like another mentioned, even though he passed away in 1995, I still collect a few things for his memory. The thing is that I think if I could ask him whether I should trade all the stuff we got together for a once in a lifetime rare item, that perhaps we may have even dreamed about owning together in the past, I think he would emphatically say YES. I know that's what I would say to my child.
Further I do think my dad might be proud of the wheeler-dealer that he raised to be able to wrangle such a great deal.

Just my two cents.
