depends wt the domain was? wat it ws used for.. how long it has been around for, what market it caters for..
We need to know the exact domain before appraising. It all depends on letters. If it is something like Star.com then it is worth thousands but if it is something like XVXY.com then it is worth less than reg fee.
Well, depends on the name. Porn.com is with a ton of money, ZQXW.com is not worth more than reg fee if you find a buyer
