The Magic 50p coin (often nicknamed The Queen's Nose) refers to the magical wish granting 50p coin at the centre of the series. Wishes may not turn out the way the weilder desires. Selfish wishes are more likely to go wrong and turn out badly for everyone involved. Wishes become facts and cannot be reversed without using another wish. The wishes granted will also affect those around the weirder. It seems as though each wish keeps renewing itself, unless it is reversed. I.E. Harmony loses Anita and Lucky, gaining Monty, she also regained another bike after the first got broken when she was hit by a truck.
