The domain market is can be shady one day and right on target the next.
You have some of the best 4 letter .com's i have ever seen,you could sell those alone for $xx,xxx or more.I would try and develop Kansascitypages.com it's a real winner!!!
cubaindex.com bottom $x,xxx
Remember if it's a .com,.org,or net and it doesn't have any slashes or alot of dots and numbers,you can count on a value of $x,xxx or higher.all other extentions are dictated by what ever price the buyer feels is appropiate.There maybe tm issues on kansascitypages.com i would check into it before investing any money.
