You can start with different domain name value calculators. May not be totally accurate, but it'll give you an idea. https://www.freevaluator.com/ - I was actually surprised to find out that it lists an estimate value for that domain at $10K. http://www.statchest.com/grade.net.html on the other hand says it's worth $1K Based on just that research I can safely assume it can go for $1K-$2K. It can also go for next to nothing if you can't find the right buyer.
