9 misprints that are worth a ton of money. Do you have a copy?

Typos can do more than damage the credibility of a publication. Penguin books in Australia recently had to reprint 7,000 copies of a now-collectible book because one of the recipes called for "salt and freshly ground black people." Correcting that typo will empty the publisher's pockets of nearly $19,000. But if you find a book with a similar mistake, it could fill yours.

When typos and mistakes appear, they're usually corrected quickly, sometimes even during printing. This makes them extraordinarily appealing to collectors, who want to own the very first copies of a work, says Vasilis Terpsopoulos, manager of the rare book department at New York City's Strand Books.

Check your personal library shelves and garage sales for these rare editions, because when publishers fail to recall every incorrect copy, collectors can make a windfall.
