If you had a treasure chest, what would be in it?

There was this touching scene from “Throw Mama From the Train” where the Danny Devito character shares his treasures with his new friend. It was an assortment of odd things that had special meanings to him.

I want to start  own treasure chest. I have some special coins and tokens to start it off. Tokens from Chuck E Cheese when I was a kid, a silver dollar minted the year I was born. Stuff like that.
