a.) The name is not pronounceable. Not to me at least.
b.) It has non premium letters.
c.) Past sales of such names indicate DNPs appraisal to be quite true.
d.) There are still some LLLL.coms left to reg. Once they're all bought out, perhaps you can get $20-25 for it.
Please try and understand that names are appraised here primarily on the reseller value. You might very well get an end user for this name who would be willing to pay 5k for it. But as it stands today, it won't go for over $20 in the reseller market.
