no.com is one of the centralnic.com domains. And they sell registration at the third level. They have a whole bunch of "country code" including uk.com, us.com etc.
The trouble is this clause in thier agreement
" 13 If the registrant for the domain name changes, the new registrant must re-register the name and pay the full registration fee. CentralNic accepts no liability and shall not be responsible if a third party registers the domain name before such re-registration."
In effect saying you cannot sell it. So the appraisal right now is $0
Now if history is any indication, registries start with very restrictive clauses and then relax them when they see the potential for revenue. So they may in the future change this rule and your domain will be worth something.
Also I must add that search engines do list sub domains including "new.net". What they do is list the whole domain ie logical.arts.new.net as opposed to logical.arts. This is an actual new.net site listed in google, with a PR of 4
