is obviously a typo. value depends on the numbers of visitors (and clicks you get from it). 20 a day is not too bad but hard to set a value from the name itself.
i cant give a exact valuation but its a good typo (i just brought 5company.com and fiveCompany.com and im trying to figure out myself a value for it) if company.com is developed in to a site then you will have more number of hits, and probably people who buy company.com might buy it off from you
look at 3 months parking revenue, evaluate your typins & overall traffic.... no appraisal possible from me as if it does get traffic I would have to se PPC avg
