I used to collect "precious" things when I was a kid, too... I still regret losing the little brass key my grandmother gave me. Although I recently found something that I once that was beautiful and magical and lost forever... and it turned out to be a rather tacky earring. I'm keeping it in my little box of treasures, of course.
My current "sacred objects"... hm. My grandmother's rolling pin, which I do use (although I nearly got in a fight with my housemate who wanted to thwack at a coconut with it.
) The pride bracelet I bought when I was still only half out of the closet... I don't wear it any more, but I'll always keep it. A shell that my best friend gave me in fourth grade. And I can't bear to throw out my old teddy bear, though he's a very battered-looking creature these days.
I'm sure I have more, scattered here and there throughout my life, but those are the ones that come to mind.
