Well, smsworld.net sold for $1,488, but that 10 years ago. SMS was the thing back then, it's becoming outdated with other messaging formats today. There doesn't appear to be an established site for the king domains, so there isn't an end-user there. Also, .org domains are just not that valuable unless there is a really popular keyword right now that is attached to it. That being said, I don't see any value here unless you somehow find an end-user for them.
