Filter is right. I appraise it a bit higher though as 64M (64 million) is hot for to many reasons to elaborate on. Just do a Google search as I just did and discover for yourself. To an end user I would say 2k plus is a reasonable price. To us whole sellers, exactly what Filter said is correct IMO but who sells to whole sellers? I try to avoid it. Email every company that runs ads in your domain and help them to understand why they need your domain and how they save money in the long run via buying your wonderful domain. If you help the advertisers learn, they appreciate it and usually pay a little more wholeheartedly.
