Do any of you have a lucky charm? And if so, what is it?

And I don’t mean the “magically delicious” kind.
I’m don’t consider myself to be superstitious but I must admit I always have two items with me. One is my lucky $1 Sacajawea coin and the other is this oriental health charm that looks like a chinese yuan (with the square hole in the middle). I never go anywhere without them.
