I'll take a stab at this and assume that you're referring to "coal", not "coel". :hehe:
As for your domain, I like it. Registered since 1997. Only problem I can see with it is that it can, as seen above, be easily confused with "coal". Also, I don't see any meaning behind it.
However, it is a pronounceable LLLL.com (cvvc at that) with solely premium letters. Between that and its age, I could see it fetching low $x,xxx.
