Yeah, I know it's Mike Ribeiro, better known for his diving penalties than most anything else.

Yeah, I know he now plays for the Dallas Stars, not the Montreal Canadiens.

And, yeah, I know that Bruins fans hate him.

See that little 04/10? That's what makes it so special. Only nine others exist in the world. Talk about rare, eh? Valuable, too.
