Typos really only have value if the real spelling has a lot of traffic and the typo version can make money via parking. Yes consignment.com sold for a lot but it is currently parked, so I can't judge its traffic. For example, facebook gets millions of hits per day, so owning facebok.com or facbook.com makes a lot of sense. Your best bet is to park your version and hope for some parking traffic and revenue. If not, then it most likely has little to no value. Best of luck.
