It is apparent that some of the posts that make it up to the trivia section are written by idiots. You're right. Why would the filmmakers deliberately put a dollar sign in as a hidden message in a film that is based on a Dickens novel,is set in England and produced and directed by the British. These are the same folks who think that one of the guys who played a munchkin in the Wizard of Oz hung himself on the set and that accidentally made it into the movie.
