I have a few aged domains, and aways in the market to sell these or to buy more. What is the market like for these and is it in the open or all underground? The obvious channels seem lacking. Need some signals sticky or otherwise.
I've been looking into this lately - and I found a place called afternic.com where you can sell domains pretty cheaply - they have a list of recently sold domains and you'll be amazed at how much some can still go for. Ebay also has a category for selling domains, although it looks like very few listings actually get sold - mostly people trying to scam people into buying a crapola domain for $5000.
There are so many people that have domains and have hard time selling them at high prices. However, I also think that there is a shortage of good domain names, so if you got something good, then it should sell if you can find the right buyer. My suggestion is to try and post it in as many places as you can as far as domain brokers and Ebay type places. Post for sale sign on your domain and WHOIS record and wait for the day until someone contact you. If you want to get a good price, then don't rush.
