Horse shoes are only lucky if the ends are pointed up. If they're pointing down the luck pours out.
Four leaf clovers.
Caowyth makes a good point though in that good luck symbols can be very personal. A person can have a lucky penny, troll doll, rock, pair of underwear etc. I used to have a Magic Square I carried to ward of wolf attacks. Its magic must have been really strong since even though I lost the square I've never been attacked by a wolf.

I think this one is confused... at that point you've already gotten lucky.

I know that statues of elephants are lucky if the trunk is pointed upwards. Other that that, all I know has been covered.
Vaughn on Alias said that spiders were lucky once...I didn't see that one on the list
(This is off-topic but not...My RPG group had a set of stuffed goslings that we would pat on our dice before a roll, because one night we used one as a stand-in for an absent player, and it rolled a natural 20. Only that one was lucky, though.)
Crickets and spiders in the house may be considered good luck, but I'll be squishing them, thankyouverymuch.
Some from Poland:
New Year's Day - when you get out of bed, make sure that your right foot touches the floor first when getting up from bed. It will bring you a lot of good luck the whole year.
Easter Monday - there's a tradition that on Easter Monday you go around splashing people with water. If you get splashed, you have good luck the rest of the year.
Storks
Horseshoes
Spiders
Linden Tree
Hay
And, our DM is lucky, for we, the players in his campaign... he tends to roll ones. A lot. Even with a brand new set of dice. That's weighted to roll only 6's.

In addition, elephants should always face the entrance of the room. An elephant with it's back to the entrance is considered bad luck for anyone who enters.
