I know godaddy appraisals value are based on past sale like there are too many website with similar domain like dos1.com.ph is a consultancy company and dos1.com is listed for 10000$ on premiumdomain.com and dus1.com is an chinese company there are alot of company like this domain so i think it should be worth something.What does jos1 mean? Please remember GoDaddy appraisals are based on past sales, mostly. So the algorithm puts together that "Jos" sold at some point along with domains that have "1" in it. Then it puts together those facts and puts out that appraisal. It is definitely not an indicator of the worth of your domain.
So unless you have a good plan for it, it's valueless.
