I saw someone here late last month selling a couple of domains. Why don't you take each of them one by one, put up a page of targeted text and preview pictures, let them sit for a few months and collect some search engine traffic, and then, try and sell them.

I think a domain itself isn't going to be worth a lot unless it's a spectacular domain. But if you've got a domain with some content and it's passed through Google's aging filters, then it's worth something.
