In folklore, the silver bullet is supposed to be the only kind of bullet for firearms that is effective against a werewolf, witch, or other monsters. Sometimes (not always) the silver bullet is also inscribed with Christian religious symbolism, such as a cross or the initials "J.M.J" (Jesus, Mary, & Joseph).

Famous quotes containing the words silver and/or bullet:
“There is probably not more than one hundred dollars in cash in circulation today. That is, if you were to call in all the bills and silver and gold in the country at noon tomorrow and pile them on the table, you would find that you had just about one hundred dollars, with perhaps several Canadian pennies and a few peppermint Life Savers.”
—Robert Benchley (1889–1945)
“It’s not the bullet with my name on it that worries me. It’s the one that says “To whom it may concern.””
—Anonymous Belfast Resident. quoted in Guardian (London, Oct. 16, 1991)
