This is pretty good actually. Investing sites are usually valued quite high in my experience.
Easily a $x,xxx site.
I'd say if you wanted a quick sale, you could offload it for $1,000-$2,000. If you're willing to wait and try lots of different outlets for selling you could possibly bring in $2,000-$3,500.
Estibot says it's valued at $6,700. However, realistically, I can't see this valuation being met unless you worked in a little content and sold the whole thing as a site with some traffic and sales (there's multitudes of affiliate products to match this type of domain name).
Best of luck.
