I hate to say "reg fee" because those are definately better than "sadfsdaflkj.com" which is alos "reg fee". But you probably won't sell them for more than $20 or so.
I'm sorry to say that none of those have much of any value. :imho: I would contact your registrar and get a refund if possible.
I would recommend that you observe the industry a bit more before making a lot of regs. Browsing the Buy/Sell/Trade forums can really be quite helpful in my opinion, as you can see what types of names actually sell and whatnot.
Good luck! If you ever want some advice about whether or not a domain is worth registering, please feel free to PM me. Don't worry, I won't steal anything.
