Alligator feet are regularly used in the South to increase gambling luck. Like the ever-popular rabbit foot, also considered lucky for gamblers, the alligator foot may worn as a key chain charm or carried in a mojo bag along with such natural curios as rattlesnake rattles, badger teeth, bat hearts, nutmegs, buckeye nuts, Lucky Hand roots, five-finger grass, John the Conqueror roots, and lodestones dressed with magnetic sand.
The use of alligator feet as gamblers' lucky charms seems to be an American notion, for alligators are indigenous to the Americas. I can find no discernible precedent for the custom in African, European, or Asian folklore, although the "clutching hand" effect of these feet resembles on a larger scale the appearance of the Lucky Hand root, a distinctively African-American gambler's charm. The alligator's near-relative, the crocodile, appears on a penis amulet from Thailand that is worn for personal strength and mastery.
