I haven’t had the chance to read the board in a while. Just glanced at this. I’ve owned over 1,000 domain names in the past 20+ years. Many I’ve sold, some I’ve used. Many I still pay the annual fees on. The short answer on the value just depends what they are willing to pay.
I wouldn’t say this is one of those super valuable domain names that tons of people would want. The best strategy is throw out some super high offer and see what they counter back with as a best offer.
I’ve also purchased a few domain names from other people. Some very reasonable for $1,500 for what I thought were desirable domain names. All the way up to $15,000 for other really desirable domain names.
Just make sure you use an escrow service if you do sell so you are both protected.
