Common good luck charms include wishbones, horseshoes, rabbits' feet, pennies and four-leaf clovers. There are many different myths that explain why these items are considered fortuitous.
In the past, some people believed that chickens could predict the future. Two people make a wish while pulling opposite ends of a chicken's collarbone. The wish of the person that receives the larger half will come true. Horseshoes are lucky because they are formed with iron and fire, which are considered magical. Rabbits' feet are an essential ingredient in some magical spells. Pennies are a type of money, which represents power. Four-leaf clovers are lucky because they are rare.
