I think that, in general, .org domains value is already very low and, in my modest opinion, it is going to further decrease on next future.
Said that, there are, as always, exceptions and this domain, Authorized.org is one of them because the name and the extension complement each other resulting in a meaningful and memorable name.
A directory of authorized organizations looks to be its natural use but other ones might sucessfully match the name.
Coming to numbers is always the more difficult task but I would say that fluctuations on the $300 range could be a possible amount for quick (or reseller) sale, while $1,500/$2,000 range could apply for retail sale.
Good luck,
