Lucky Penny: Pennies have come to be known as lucky because of the popular Depression-era phrase, "Find a penny, pick it up, all day long you'll have good luck." May 23rd is Lucky Penny Day.
Four-Leaf Clover: This rare variation of the three-leaf clover is said to bring good luck to its finder, especially when found accidentally. There may be one four-leaf clover in a patch of 10,000 three-leaf clovers. According to legend, each leaf of the clover represents something: the first stands for faith, the second for hope, the third for love, and the fourth for luck.

Rabbit’s Foot: Most people around the world believe carrying a rabbit’s foot can bring good luck. This belief most likely originated with the Celts around 600 B.C.

Ladybug: Many cultures believe that if a ladybug lands on you, you will have good luck, especially if you do not brush it off. In Austria, they’re even called "Glueckskaefer", or "lucky bugs". Some believe that if a man and woman see a ladybug at the same time, they will fall in love. To some of the superstitious, the deeper the red and the more spots the ladybugs have, the luckier they are and the more prosperity they will bring.
Throwing Salt Over Your Shoulder: According to the Bible, throwing salt over your shoulder is supposed to be a way to keep the devil at bay. Traditionally, if you spill salt, use your right hand to throw some over your left shoulder and you will blind the devil from seeing your error.

Wishbone: Though usually an American Thanksgiving tradition played after the turkey has been consumed, the two-person, tug-of-war-like game of pulling apart the wishbone began with the Etruscans, long before America was discovered, almost 2400 years ago. When you and an "opponent" grab each end of the wishbone and pull in opposite directions and the bone breaks, the person who ends up with the longest piece of bone will have good luck. The phrases "I can't get a break" and "I need a lucky break" come from this competition.
Nautical Star: The nautical star, or North Star, provides guidance, and is a good luck symbol among sailors. In biblical lore, it gave direction to the promised land.
