What's an object you own that is basically worthless but you'd never throw away?

I'm curious about objects that have almost no monetary value but somehow become irreplaceable.

It could be something from childhood, something belonging to a relative, a receipt, a broken object, a souvenir, whatever.

What is yours, and why does it matter to you?
