http://www.yourdictionary.com/library/misspelled.html I understand value of misspelled company names. But is there value in misspelling common words? If so I can have fun in my spare time trying to find some words people misspell.
Value of Mispelled Company names = Potential TM issues. Value of common words, it all depends on traffic & revenue. Otherwise, if none, it's worthless.
It has lots of value provided you have good collection of misspelled domains. In 2005 Marchex paid $ 164 Million to Name Development Ltd for a portfolio of over 100000 misspelled domain name. Ani
That has traffic & revenue only. It's very easy to go out there & just register mispelled domains that don't have that.
