Well you have to define it a bit more. By weight? By amount paid? By total cost for ever?
AS of the close of trading today, Apple Inc. is capitalized at $659 Billion. And it would take probably a 255 premium to but the whole company. So it would cost you about $825 Billion to buy.
A lot of people would say an ex spouse. Others would say kids.
@Adirondackwannabe Yes, those are priceless but they cost you nothing and the return on investment is immeasurable. And, even if someone offers to sell that to you, you’re getting a fake, not the real thing.
