domain "NoBlock.com" Appraisal Request

This domain is currently forwarded to a large website about my services as a Certified Professional Resume Writer. I am also the registrant of "NoBlock.net" (where another site, about my technical writing services, is hosted) and "NoBlock.ca" (currently blank). None of the above websites are currently getting significant traffic, so I don't think they will affect the value of their respective domains, but I'm mentioning them for the sake of transparency. I think the availability of the dot-net and dot-ca versions may act as an incentive to purchase the dot-com. I believe the dotcom is valuable, but don't want to delude myself into thinking I am going to get a significant amount of money for it and end up disappointed.

I'm a brand new member of this community (having joined today) and would be grateful for any suggestions or ideas with respect to the above-mentioned domains.
